HYDROBORATION DE CARBURES ALLENIQUES PAR LE BORA-9 BICYCLO(3,3,1) NONANE. SYNTHESE DE DIALKYL ALLYL BORES

10.1016/S0040-4039(01)91930-6

The study investigates the hydroboration of allenic compounds using 9-BBN (bora-9 bicycle (3,3,1) nonane) as the hydroborating agent. The researchers examined the hydroboration reactions of five different allenic systems, which include compounds like phenylallene, n-butylallene, dimethyl-1,3 allene, and others with varying steric hindrances. The aim was to determine the influence of steric and electronic factors on the regioselectivity and stereoselectivity of the hydroboration process. The results showed that as steric hindrance increased, the percentage of diaddition products decreased, and in some cases, only monoaddition products were formed. The products were characterized through complexation with pyridine and oxidation in basic conditions, revealing that the hydroboration was both regio- and stereospecific, yielding allylic alcohols with pure stereochemistry. The study also briefly explored the impact of electronic factors by examining the hydroboration of methoxyallene, although the structures of the products from this reaction were not fully determined.
