标 题 :Synthesis of alkenes from enamines via hydroboration
发明人：GORALSKI CHRISTIAN T; SINGARAM BAKTHAN; BROWN HERBERT C
权利人:PURDUE RESEARCH FOUNDATION; DOW CHEMICAL CO
摘要:Alkenes are prepared by the hydroboration of enamines followed by an elimination reaction to form the alkene. This process has wide applicability and is useful for the stereospecific synthesis of [Z] isomers. It is preferred to use 9-borabicyclo[3.3.1 nonane as the hydroborating agent and to use methanol to catalyze the elimination reaction.
