First Examples of Spirooxaphosphirane Complexes

The reaction of a transient Li/Cl phosphinidenoid pentacarbonyltungsten complex (R = CH(SiMe3)2) with cyclohexanone, cyclopentanone, and cyclobutanone yielded the novel, atropisomeric spirooxaphosphirane complexes 3a,b–5a,b, while 2,3-diphenylcyclopropenone furnished selectively the 1,2-dihydrophosp...

Description
Summary:The reaction of a transient Li/Cl phosphinidenoid pentacarbonyltungsten complex (R = CH(SiMe3)2) with cyclohexanone, cyclopentanone, and cyclobutanone yielded the novel, atropisomeric spirooxaphosphirane complexes 3a,b–5a,b, while 2,3-diphenylcyclopropenone furnished selectively the 1,2-dihydrophosphet-2-one complex 6. All complexes have been characterized by heteronuclear NMR, mass spectrometry, and single-crystal X-ray analysis in the case of 4a, 5a, and 6.
