Jaiswal, Kuldeep;Groutchik, Kristina;Bawari, Deependra;Dobrovetsky, Roman research published ã€?An “On-Demand”, Selective Dehydrogenative Borylation or Hydroboration of Terminal Alkynes Using Zn²⁺-based Catalystã€? the research content is summarized as follows. Cationic three-coordinate zinc tris(picolyl)phosphine complex catalyzes either dehydrogenative borylation of α-alkynes yielding alkynylboronates, or hydroboration affording vinylboronates, depending on catalyst load and reaction temperature An air-stable dicationic Zn²⁺ complex [Zn[P(CH₂py)₃]][B(C₆F₅)₃]₂ (1) in a tripod-type ligand with non-bound phosphorus base and three pyridinyl “arms” (TPPh) was synthesized. Remarkably, while 2 mol% of 1 at room temperature selectively catalyzed dehydrogenative borylation of terminal alkynes with HBPin, a lower loading of 1 (0.5 mol%) at 90° selectively promoted hydroboration reaction of the same alkynes skipping the dehydrogenative borylation step. The mode of action of 1 was proposed based on exptl. observations as well as the mechanism of dehydrogenative borylation was studied by DFT computations.

Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Name: Methyl 2-cyanoacetate.

Jackson, Grayson L.;Dennis, Joseph M.;Dolinski, Neil D.;van der Naald, Michael;Kim, Hojin;Eom, Christopher;Rowan, Stuart J.;Jaeger, Heinrich M. research published �Designing Stress-Adaptive Dense Suspensions Using Dynamic Covalent Chemistry� the research content is summarized as follows. The non-Newtonian behaviors of dense suspensions are central to their use in technol. and industrial applications and arise from a network of particle-particle contacts that dynamically adapt to imposed shear. Reported herein are studies aimed at exploring how dynamic covalent chem. between particles and the polymeric solvent can be used to tailor such stress-adaptive contact networks, leading to their unusual rheol. behaviors. Specifically, a room temperature dynamic thia-Michael bond is employed to rationally tune the equilibrium constant (K_eq) of the polymeric solvent to the particle interface. It is demonstrated that low K_eq leads to shear thinning, while high K_eq produces antithixotropy, a rare phenomenon where the viscosity increases with shearing time. It is proposed that an increase in K_eq increases the polymer graft d. at the particle surface and that antithixotropy primarily arises from partial debonding of the polymeric graft/solvent from the particle surface and the formation of polymer bridges between particles. Thus, the implementation of dynamic covalent chem. provides a new mol. handle with which to tailor the macroscopic rheol. of suspensions by introducing programmable time dependence. These studies open the door to energy-absorbing materials that not only sense mech. inputs and adjust their dissipation as a function of time or shear rate but also can switch between these two modalities on demand.

Name: Methyl 2-cyanoacetate, Methyl cyanoacetate is an alkyl cyanoacetate ester.
Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Knövenagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α -cyanocinnamic esters.
Methyl Cyanoacetate is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate (M287290); a compound used in the synthesis of DPP-IV inhibitors for treating type 2 diabetes., 105-34-0.

Iwumene, Ndidi U. N.;Moseley, Daniel. F.;Pullin, Robert D. C.;Willis, Michael C. research published ã€?Diverse saturated heterocycles from a hydroacylation/conjugate addition cascadeã€? the research content is summarized as follows. Rhodium-catalyzed hydroacylation using alkynes substituted with pendant nucleophiles, delivers linear α,β-unsaturated enone intermediates with excellent regioselectivity. These adducts are used to construct a broad range of diversely substituted, saturated O-, N- and S-heterocycles in a one-pot process. Judicious choice of cyclisation conditions enabled isolation of O-heterocycles with high levels of diastereoselectivity. A variety of derivatization reactions are also performed, generating functionalized hydroacylation products. This sequence serves as a general approach for the synthesis of fully saturated heterocycles.

Ivanov, Konstantin L.;Melnikov, Mikhail Ya.;Budynina, Ekaterina M. research published �Reductive Knoevenagel Condensation with the Zn-AcOH System� the research content is summarized as follows. An efficient gram-scale one-pot approach to 2-substituted malonates and related structures were developed, starting from com. available aldehydes and active methylene compounds The technique combines Knoevenagel condensation with the reduction of the C=C bond in the resulting activated alkenes with the Zn-AcOH system. The relative ease with which the C=C bond reduction occurs can be traced to the accepting abilities of the substituents in the intermediate arylidene malonates.

Ivanov, Konstantin L.;Tukhtaev, Hamidulla B.;Tukhtaeva, Feruza O.;Bezzubov, Stanislav I.;Melnikov, Mikhail Ya.;Budynina, Ekaterina M. research published ã€?One-Pot Synthesis of γ-Azidobutyronitriles and Their Intramolecular Cycloadditionsã€? the research content is summarized as follows. Efficient gram-scale, one-pot approached to azidocyanobutyrates and their amidated or decarboxylated derivatives was developed, starting from com. available aldehydes and cyanoacetates. These techniques combine (1) Knoevenagel condensation, (2) Corey-Chaykovsky cyclopropanation and (3) nucleophilic ring opening of donor-acceptor cyclopropanes with the azide ion, as well as (4) Krapcho decarboxylation or (4′) amidation. The synthetic utility of the resulting γ-azidonitriles was demonstrated by their transformation into tetrazoles via intramol. (3+2)-cycloaddition A condition-dependent activation effect of the α-substituent was revealed in that case. Thermally activated azide-nitrile interaction did not differentiate the presence of an α-electron-withdrawing substituent in γ-azidonitriles, whereas the Lewis acid mediated (SnCl₄or TiCl₄) reaction proceeded much easier for azidocyanobutyrates. This allowed us to develop an efficient procedure for converting azidocyanobutyrates into the corresponding tetrazoles.
