✦ Synopsis

Ab initio molecular orbital calculations at the QCISD(T)/&311+ +G(d,P)//MP2/6-31G(d,p)+ZPE level show that the suprafacisl 1,3-hydrogen shifts in the I-phosphapropene-vinylphosphine ( H&-CH=PH=H,C=CH-PH2) and degenerate 1,3diphosphapropene (H*P-CH-PH=HP=CH-PH,) rearrangements do not only exist but they also compete favourably with the corresponding antamfacial pathways.

The rate constants for the 1,3-and 1,Mgmatropic hydrogen shifts of the phot&Fries rearranged intermediates of phenyl acetate produced by laser flash photolysis at 266 nm were directly measured in several solvents. The rate constant for the 1,3hydrogen shift (3.6 s-l) was faster than that for the l&s

The reaction of 3-pyrrolidino-l,2,4-triazine 4-oxide with ammonia leads to the product of tele-substitution of pyrrolidine -5-amino-1,2,4-triazine 4-oxide. Sigmatropic shift of hydrogen postulated for such reactions has been proved by isolation of key intermediates.
