A Diborylcarbazolyl Ligand for Stabilizing Low-Coordinate and Low-Valent Metal Complexes
Abstract
High Resolution Image Download MS PowerPoint Slide We report the synthesis of a novel ligand L (3,6-di- tert -butyl-1,8-bis(dimesitylboryl)carbazolide) based on a carbazolyl scaffold bearing two sterically demanding boryl groups at the 1,8-positions. This diborylcarbazolyl framework effectively supports a range of transition metal complexes, including two-coordinate halide complexes LM II Cl [M = Fe ( 2 ), Co ( 3 ), and Zn ( 4 )], trinuclear complex ( LCr ) 2 ( CrCl 4 ) ( 5 ), and pseudo-one-coordinate complexes LM I [M = Ni ( 6 ) and Cu ( 7 )]. Coinage metal complexes derived from L exhibit a preference for two-coordinate geometries, as demonstrated by the isolation of LMPPh 3 [M = Ag ( 8 ) and Au ( 9 )] and LCu ( DMAP ) ( 10 ).
