Abstract
Our investigations to be presented here have their origin in a number of former results: The formation of [(Me3Si)2P]2SiMe2 [1] and its rearrangement to P4(SiMe2)6 (a molecule with adamantane structure) and P(SiMe3)3, the formation of P7(SiMe3)3 and of some cyclic phosphanes by the thermally induced rearrangement of [(Me3Si)2)P]2SiMe2 [3], and the formation of P7(SiMe3)3 by reacting P4 with Na/K-alloy and Me3SiCl. After finding LiP(SiMe3)2 to be such a versatile reagent we turned to elucidate synthesis and chemical behaviour of LiP[P(SiMe3)2]2.
