摘要：

The beta -effect of silicon was shown to be a determining factor for the regioselectivity of the Pauson-Khand reaction of alkynylsilanes with allenes. This electronic effect accounts for the formation of 3-trimethylsilyl-4-alkylidenecyclopentenones observed from monosubstituted allenes. (C) 2001 Elsevier Science Ltd. All rights reserved.
