Syntheses of 1,2-Thiaphospholes and Their Thermal and Lewis Acid-Promoted Addition Reactions

3,5-Di-substituted 1,2-thiaphospholes were efficiently prepared by treating 2,9-dithia-1-phosphabicyclo-nona-3,7-diene 1-sulfides with n-Bu3P.The thiaphospholes reacted thermally with norbornadiene, norbornene or dietyl azodicarboxylate to produce

Different thermal reactivity of a 1,2-thiaphospholo[a]phosphirane in free and metal carbonyl complexed form

The W(CO)5 and Fe(CO)4 complexes of the bicyclic phosphirane 3,5,6,6-tetraphenyl-1-phospha-2-thiabicyclo-[3.1.0]hex-3-ene undergo a thermal 2-phenylphosphirane → dihydrophosphaisoindole ring expansion, while the free phosphirane suffers both a [2 + 1] cycloreversion and a fragmentation yielding a butadienyl sulfide.

Preparation and Reactions of 1,2-Thiaphospholes

Treatment of 2,9-dithia-1-phosphabicyclo-nona-3,7-diene 1-sulfides with n-Bu3P afforded 1,2-thiaphospholes in good yields.The thiaphospholes reacted thermally with norbornene to produce 1:2 double Diels-Alder cycloadducts, whereas they reacted with
