N-acyl- and N-alkoxycarbonylaminophthalimides are efficiently used as acid partners in Mitsunobu reaction. This reaction allows them to be alkylated by primary, secondary or benzyl groups. A final dephthaloylation step results in an efficient method for the preparation of 1,1-substituted hydrazines.
