preparation of fluoroalkyl allylamines or alpha,beta-unsaturated ketones by an olefination reaction of primary enamine phosphonates and aldehydes, followed by selective reduction with hydrides or hydrolysis, is reported. Fluorinated beta-amino nitriles are also obtained by an olefination reaction of primary enamine phosphonates with aldehydes and subsequent addition of metalated acetonitrile.
