  Photochemical Isomerizations of 5-Alkylidene-4,5-dihydro-3H-1,2,4(λ3)-diazaphospholes (4-Phosphapyrazolines): (5→4) Ring Contraction Generates Azomethineimine Dipoles

  摘要：

  UV irradiation of the title compounds 1a-d results not in extrusion of molecular nitrogen, but in a skeletal rearrangement generating amino(imidoyl)phosphanes 2a-c from 1a-c and 2-hydrazinobenzo[b]phosphole 4 from 1d. The first step in these isomerizations is an unprecedented (5-->4) ring contraction of 1 to form the semicyclic azomethineimine dipoles 10 incorporating a 1,2,3-diazaphosphetidine ring. Dipoles 10a-c, but not 10d, can be observed by NMR spectroscopy after brief irradiation of the precursors. Furthermore, they could be trapped by [3+2] cycloaddition reaction with dimethyl acetylenedicarboxylate to give the bicyclic 1,2,3-diazaphosphetidines 12a-c, and, in the case of 10a and 10c, also the dihydrophospholes 13a,c resulting from a second [3+2] cycloaddition.
