Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.3032-92-6, formula is C9H5N, Name is 4-Ethynylbenzonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Name: 4-Ethynylbenzonitrile.
Cui, Jian-Fang;Yu, Qiong;O, Wa-Yi;Huang, Li-Wu;Yang, Bin;Wong, Man-Kin research published 《 Synthesis of 1H-isoindoliums by electrophile-mediated cascade cyclization/iodination of propargylamine-based 1,6-diynes》, the research content is summarized as follows. A highly regio- and chemoselective synthesis of 1H-isoindoliums I [R1 = Ph, 3-MeC6H4, 3-thienyl, etc.; R2 = CH2, CH(Me), O; R3 = H, 6-Me, 5-Cl, 6-Cl, 6-MeO, 6-CF3] through a facile and novel cascade cyclization reaction of propargylamine-based 1,6-diynes under mild conditions had been developed. Different functional groups were compatible under the optimized reaction conditions, giving the corresponding products in up to 94% yields. Upon treatment with a base, the alkyne moiety of 1H-isoindoliums could be further transformed to allenes II [R4 =CH2, O; R5 = Ph, 4-FC5H4, 4-NCC6H4; R6 = H] in excellent yields.
Name: 4-Ethynylbenzonitrile, 4-Ethynylbenzonitrile is a simple benzyl alkyne compound potentially useful as a synthetic fragment and as a test compound for cross-coupling protocols. 4-Ethynylbenzonitrile has been described as a model compound for studying hydrogen bond formation in multifunctional molecules, as it contains four hydrogen bonding sites of which three are π-acceptors.
4-Ethynylbenzonitrile is a useful research compound. Its molecular formula is C9H5N and its molecular weight is 127.14 g/mol. The purity is usually 95%., 3032-92-6.
