The selective functionalization of alkanes and alkyl groups is a major goal of chemical catalysis. Toward this end, a bulky triphosphine with a central secondary phosphino group, bis(2-di- -butyl-phosphinophenyl)phosphine ( P PP), has been synthesized. When complexed to iridium, it adopts a meridion...
