Abstract

A Rh complex of a bulky diarylamino-based PNP pincer ligand is a robust catalyst for the dimerization of terminal alkynes and highly selective for the trans-enyne product. ... Alkyne dimerization is an attractive, atom-economical method of synthesizing conjugated enynes. 1 Conjugated enynes are attractive as building blocks in organic synthesis and components of biologically active molecules. 2 The challenge is tuning the selectivity to the desired enyne isomer (A, B or ...
