Abstract

The present study deals with the copolymerization of an amino acid-based acetylene, N-(tert- butoxycarbonyl)-l-alanine N'-propargylamide (l-1A) with the optical isomer (d-1A), achiral hexanoic acid N-propargylamide (2A), and pivalic acid N-propargylamide (3A), and chiroptical properties of the copolymers. The copolymerization catalyzed by (nbd) Rh+ [η6- C6H5B-(C6H5) 3] afforded copolymers with number-average molecular weights over 104 ...
