摘要：

Allylation of aldehydes with allyltrifluorosilanes in the presence of a wide variety of hydroxy compounds and triethylamine gave the corresponding homoallyl alcohols in regio- and stereospecific manner. Pentacoordinate allylsilicates are suggested as intermediates. The present reagent system can discriminate linear from α-branched alkanals. The structure and reactivity relationship in pentacoordinate allylsilicates is discussed in terms of Lewis acidity of the central silicon. © 1990, American Chemical Society. All rights reserved.
