New catalytic systems have been found which effect the isomerization of α-acetylenic alcohols to the corresponding α, β-unsaturated carbonyl compounds with high efficiency. These are combinations of silylvanadates with silanols or silanediols.
已经发现了新的催化体系,其可以高效地将α-炔醇异构化为相应的α,β-不饱和羰基化合物。这些是
硅烷基
钒酸盐与
硅烷醇或
硅烷二醇的组合。
