The organic synthesis using haloboration reaction 20. A simple synthesis of (2-Bromoallyl)diphenoxyborane by the bromoboration of allene and its reaction with carbonyl compounds
摘要:
Bromoboration reaction of allene with boron tribromide, followed by the treatment with anisole gives (2-bromoally)diphenoxyborane which reacts with aldehydes and ketones to give 2-bromohomoallylic alcohols in excellent yields.
