1,3-Bis(2,6-diisopropyl­phen­yl)imidazolidin-2-yl­idene

Abstract

The title compound, C27H38N2, is the first reported free imidazolidin-2-yl­idene carbene with 2,6-diisopropyl­phenyl groups in the 1,3-positions. The five-membered ring adopts a twisted conformation and the dihedral angle between the aromatic rings is 48.81 (6)°. Both isopropyl groups attached to one of the benzene rings are disordered over two sets of sites in 0.74 (2):0.26 (2) and 0.599 (8):0.401 (8) ratios
