Divergent intramolecular reactions between phosphines and alkynes

A divergent intramolecular reaction of phosphine tethered alkyne in protic solvent was developed. This provided a novel and simple access to a large variety of (Z)-alkenylphosphine oxides and phospholane oxides. Our preliminary studies suggested that these divergent reactions are closely related to the reaction condition and molecular structure. A possible mechanism of C-P bond cleavage of a pentacoordinated hydroxyphosphorane intermediate was proposed.
Intramolecular, Pd/Cu-Co-catalyzed P-C Bond Cleavage and Addition onto an Alkyne: A Route to Benzophospholes

Under Pd(II)/CuI cocatalysis, o-diarylphosphinophenylalkynes cyclize in boiling toluene via C-P bond cleavage and arylphosphination of the C≡C bond. This protocol provides an unprecedented atom- and step-efficient access to optoelectronically and biologic

The synthesis of aurated phosphindolium complexes from easy accessible 1,5-alkynylphosphine derivatives has been studied by using gold(I) complexes featuring carbene and phosphine ligands as initiators. Upon formation of the mixed phosphine NHC/phosphine
Versatile synthesis of Phospholides from open-chain precursors. application to annelated pyrrole- and silole-phosphole rings
Xu, Youzhi,Wang, Zhihua,Gan, Zhenjie,Xi, Qiuzhen,Duan, Zheng,Mathey, Fran?ois

Phospholides are easily obtained by treatment of the open-chain acetylenic phosphines shown by an excess of lithium at room temperature in THF (12 examples).
Addition of Water to o-Phenylethinyl-substituted Triphenylphosphanes and Reduction of the Formed Phosphane Oxide En-ynes
Butters, Thomas,Haller-Pauls, Irene,Winter, Werner
, p. 578 - 592 (2007/10/02)
Heating of the o-phenylethinyl-substituted triphenylphosphanes 1a - c in organic solvents containing water affords the phosphane oxides 2a - c through an intramolecular nucleophilic addition of the phosphorus to the triple bond, stereoselectively with a t
