Convenient Synthesis of W(⋮CR)X3(dme) Compounds from W(⋮CR)(OBut)3 Triple-Bond Metathesis Products
摘要:
Tungsten-alkylidyne complexes of the type W(drop CR)X-3(dme) (R = Bu-t, Pr-n, Ph; X = Cl, Br; dme = 1,2-dimethoxyethan) are prepared in 77-87% yields from reactions between W(drop CR)(OBut)(3) and BX3 in the presence of dime.
