Wang, Shichun published the artcileInfluence of the 1,3-Bis(trimethylsilyl)cyclopentadienyl Ligand on the Reactivity of the Uranium Phosphinidene [η5-1,3-(Me3Si)2C5H3]2U(:P-2,4,6-iPr3C6H2)(OPPh3), Application of Phthalonitrile, the main research area is insertion alkyne diazabutadiene unsaturated mol uranium metallocene phosphinidene complex; uranium metallaheterocycle preparation insertion unsaturated mol phosphinidene metallocene; crystal structure uranium heterocycle metallocene phosphinidene complex; mol structure uranium heterocycle metallocene phosphinidene complex.
At ambient temperature [η5-1,3-(Me3Si)2C5H3]2U(Cl)Me (3) reacts with 2,4,6-iPr3C6H2PHK in toluene in the presence of Ph3PO to yield the Lewis base supported terminal uranium phosphinidene metallocene [η5-1,3-(Me3Si)2C5H3]2U(=P-2,4,6-iPr3C6H2)(OPPh3) (4), whose structure and reactivity were probed. When it is treated with conjugated alkynes and diazabutadienes, compound 4 acts as a masked synthon for the divalent uranium fragment [η5-1,3-(Me3Si)2C5H3]2UII to give [η5-1,3-(Me3Si)2C5H3][η5-1-(CH2Me2Si)-3-(Me3Si)C5H3]U[(1-(2,4,6-iPr3C6H2)-2,5-Ph2C4HP)] (7) and [η5-1,3-(Me3Si)2C5H3]2U[N(p-tolyl)CH(P-2,4,6-iPr3C6H2)CHN(p-tolyl)] (8), resp. Nevertheless, in the presence of internal alkynes and various heterounsatd. mols. such as imines, carbodiimides, isothiocyanates, aldehydes, nitriles, isonitriles, and organic azides complex 4 affords metallaheterocycles, sulfido, oxido, and imido complexes in good yields. Furthermore, when it is exposed to the diazene PhN:NPh, complex 4 converts to the four-membered heterocycle [η5-1,3-(Me3Si)2C5H3]2U[N(Ph)P(2,4,6-iPr3C6H2)N(Ph)] (12) in good yield.
Organometallics published new progress about Aldehydes Role: RCT (Reactant), RACT (Reactant or Reagent). 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Application of Phthalonitrile.
