Borrowing hydrogen: The catalytic efficiency of phosphine-free non-bifunctional MnI−NHC complexes of chelating heteroditopicligands featuring ImNHC connected to a 1,2,3-triazole-N or tzNHC donors through a methylene spacer have been explored for coupling of diverse nitriles with alcohols by borrowing hydrogen protocol. The catalyst Mn1 containing ImNHC connected to triazole-N donor displayed higher
