  Chemistry and ligating properties of the 1,2,4-thiadiphosphole P2SC2But2

  摘要：

  New synthetic routes to the 1,2,4- and 1,3,4-thiadiphospholes, P2SC2Bu'(2), are presented. Both eta(1)-W(CO)(5) and eta(5)-M(CO)(3) complexes (M = Mo, W) of the 1,2,4-thiadiphosphole ring are described and the molecular structure of the former determined by a single crystal X-ray study is in good agreement with theoretical calculations. The thermal conversion of the eta(1)-M(CO)(5) complex to the eta(5)-M(CO)(3) complex is attributable to the entropy change in the reaction. A sequence of [4+2] and [2+2+2] cyclo-addition reactions of the 1,2,4-thiadiphosphole, P2SC2Bu'(2), with the phosphaalkyne, P=CBu' affords the tetracyclic cage compound P4SC4Bu'(4) which has also been structurally characterised.
