✦ Synopsis

When PhRP(0)N3 (R = Ph or t-Du) is photolysed in dimethylsulphide substantial amounts (22 -3276) of PhRP(O)N:SMeZand PhRP(0)NHCH2SMe are produced and rearrangement is less important than in benzene. Phosphinic azides eliminate N2 on photol.ysis. The major pathway in methanol involves rearrangement to a metaphosphonimidate which is trapped by the solvent e.g. azide (L) gives (2) via (2?).ls2 In benzene (1) gives
