โœฆ Synopsis


The hydroboration of allylsilanes is highly stereoselective in the sense (3 -t 4 and 6 + .I), especially with 9-BBN as the hydroborating reagent.

The products can be converted stereospecifically into 1,3-diol derivatives (5 and 6).

Allylsilanes usually react with electrophiles in the stereochemical sense (1). 2-4 We now report that they generally undergo hydroboration with the same stereochemistry, so that it is E+ R'sSi

The hydroboration of most types of allylsilane is highly selective for the formation of the product having the silicon and boron in a 1,3 relationship when the hydroborating agent is 9-BBN. There is only a low degree of correlation between the difference in the chemical shifts of the trigonal carbon
