Abstract

The first bis(cyclotriphosphano)phosphane (t-BuP)2P -P(Me)-P (t-BuP)2 (1) has been synthesized by reacting (t-BuP)2PSnMe3 with MePCl2 in the molar ratio 2:1. With equimolar amounts of the reactants the chlorom ethylphosphino cyclotriphosphane (t-BuP)2P -P(Me)Cl (2) has been obtained. 1 represents a novel P7R5 structure type in addition to the types already known [4, 5]. The NMR parameters of 1 and 2 are reported and discussed
