DOI: 10.1021/acs.organomet.6b00780
Abstract: The dearomatization of naphthalene and anthracene is explored by their η2 coordination to {TpMo(NO)(MeIm)} and {TpMo(NO)(DMAP)} (where Tp = hydridotris(pyrazolyl)borate, MeIm = 1-methylimidazole, and DMAP = 4-(dimethylamino)pyridine). The DMAP and MeIm complexes have nearly identical… read more here.
