UV irradiation of the title compounds 1 a ยฑ d results not in extrusion of molecular nitrogen, but in a skeletal rearrangement generating amino(imidoyl)phosphanes 2 a ยฑ c from 1 a ยฑ c and 2-hydrazinobenzo[b]phosphole 4 from 1 d. The first step in these isomerizations is an unprecedented (5 34) ring c
