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.
Synthesis of 2,3-dihydro-1-phenylbenzo[b]phosphole (1-phenylphosphindane) and its use as a mechanistic test in the asymmetric appel reaction: Decisive evidence against involvement of pseudorotation in the stereoselecting step

Racemic 2,3-dihydro-1-phenylbenzo[b]phosphole was obtained by reduction of 1-phenylbenzo[b]phosphole-1-oxide, itself derived by ring-closing metathesis of phenylstyrylvinylphosphine oxide. The title compound was then reoxidized under asymmetric Appel cond

Diphenylnitrilimine cycloaddition reactions to two phosphindoles oxides are regiospecific ans stereospecific.The approach of the dipole occurs from the less hindered diastereotopic side of the dipolarophile.

Deoxygenation of the dimer of 1-phenylphosphole oxide gives the diphosphine, whose thermal decomposition provides a useful route to r-1-phenyl-c-3a,c-7a-dihydrophosphindole.In the gas phase in the temperature range 345-370 deg C the dihydrophosphindole un
