title: Heterolytic cleavage of hydrogen molecule by rhodium thiolate complexes that catalyze chemoselective hydrogenation of imines under ambient conditions.
abstract: The bis(thiolate)Rh(III) complex having a tris(3,5-dimethylpyrazolyl)borate (Tp(Me2)) coligand [Tp(Me2)Rh(SPh)(2)(MeCN)] reacts reversibly with H(2) to form the hydridothiolato complex [Tp(Me2)RhH(SPh)(MeCN)] and PhSH. The benzenedithiolate analogue [Tp(Me2)Rh(o-S(2)C(6)H(4))(MeCN)], which can also heterolytically activate H(2), catalyzes hydrogenation of imines under ambient temperature and pressure with high chemoselectivity.
