Cyclic Phosphine Oxides and Phosphinamides from Di-Grignard Reagents and Phosphonic Dichlorides: Modular Access to Annulated Phospholanes

The reaction between 1,4-di-Grignard reagents and phosphonous(III) dichlorides is a classical method for the direct synthesis of phospholanes. Reported here is an extension of this approach to the preparation of value-added, annulated phospholane oxides, achieved through the combination of carbocyclic-fused di-Grignard reagents and readily available phosphonic(V) dichlorides. The procedure is amenable to (benz)annulation at both the 2,3- and 3,4-positions of the phospholane ring, and a variety of aliphatic, cyclic and aryl P-electrophiles are tolerated in reasonable to excellent yields.

A MILD AND FACILE SYNTHESIS OF ALKYL- AND ARYLPHOSPHONYL DICHLORIDES UNDER NEUTRAL CONDITIONS. REACTION OF BIS(TRIMETHYLSILYL) PHOSPHONATES WITH PCl5
Morita, Tsuyoshi,Okamoto, Yoshiki,Sakurai, Hiroshi
, p. 435 - 438 (2007/10/02)
Bis(trimethylsilyl) phosphonates, which are prepared from the dialkyl esters with chlorotrimethylsilane/sodium iodide, are transformed in high yields into the corresponding phosphonyl dichlorides on the treatment with phosphorus pentachloride under mild and neutral conditions.
