Synthesis and Properties of Sterically Hindered Tertiary Amines and Guanidines

Sterically hindered tertiary amines 7,8,14,17 are synthesized by reaction of the iminium salts 3,4, and 16 with Grignard compounds 5,12 or alkyllithium compounds 11,13.Hindered guanidines 24 are prepared from chloroformamidinium 22 or (dichloromethane)iminium salts 26 and primary amines 23.The pKa values of the amines 7,8,17, and guanidines 24 are measured, and their alkylation with methyl fluorosulfonate (31) is studied.
