Abstract

The ligand 1, 3-bis (diphenylphosphino)-1H-indole, L1 with palladium promotes Suzuki– Miyaura coupling reaction of chloroarenes and benzyl chlorides with arylboronic acids. Structural modification of L1 established that the phosphine group at C-3 position of indole was crucial to catalysis and its efficacy depended on the nature of the N-substituent. 31P chemical shift values of the substituted indolylphosphines appear to show a correlation ...
