Functionalized phosphoniumsalts in Wittigreactions give ethylenic amines. With aldehydes the nature of the carbon chain and of the substituents on nitrogen have no influence on stereochemistry; ethylenic ketones, give aminopolyenes. Steroids give aminosteroids if a large excess of phosphonium salt is used. Amphiphilic compounds may therefore be prepared and aminoalkyl groups may be introduced to
