The η3-allymolybdenum complexes [Mo(C5H5)(CO)2(syn-1-C3H4R)](R = vinyl or buta-1,3-dienyl) undergo BF3 catalysed carbonâcarbon bond formation with aldehydes, ketones and α,β-unsaturated ketones; applications to the synthesis of functionalized 1,3-dienes and 1,3,5-trienes are reported, and evidence for formation of an s-trans-diene as an intermediate is presented.
η3-烯丙基钼配合物[Mo(C5H5)(CO)2(syn-1-C3H4R)](R =乙烯基或丁-1,3-二烯基)与醛、酮和α,β-不饱和酮发生BF3催化下的碳-碳键形成;据报道,该化合物可用于合成官能化的1,3-二烯和1,3,5-三烯,并提供了形成s-反式-二烯作为中间体的证据。
