General description

Di-tert-butylchlorophosphine belongs to the class of phosphine ligands. It is used for cross-coupling reactions because of the flexibility of its electronic and steric properties. It plays a key role in stabilizing and activating the central metal atom and is used in reactions such as transition metal-catalyzed C-O, C-N, and C-C bond-forming reactions.

Application

Di-tert-butylchlorophosphine can be used as a ligand in:      
  • The Pd-catalyzed amination reaction with aryl halides.      
  • The Pd-catalyzed Suzuki-Miyaura cross-coupling of arylboronic acids with aryl bromides and chlorides.

Pro-azaphosphatrane 1a [P(iBuNCH2CH2)3N] reacts with iodine under mild conditions to give [IP(iBuNCH2CH2)3N]I in excellent yield, which on subsequent reaction with ammonia followed by deprotonation with KOtBu provided HN=P(iBuNCH2CH2)3N (3a) in quantitative yield. Reaction of 3a with R'2PCl afforded sterically bulky
