The intermediate alkyl radical produced by the addition has a choice of paths to follow It may attack X—Y, abstracting Y and leaving a new X- to add to another olefin (Equation 9.81), or it may itself add to the next olefin (Equation 9.82). There are also other possibilities, which we shall consider later, such as reversal of the original addition, or some other fragmentation. The nature of the products will depend on the relative rates of processes 9.81 and 9.82. If we...

Cationic 2-azaallenylidene complexes such as 181 are capable of accepting nucleophiles at the y position as shown in Eq. (148) (166). In fact, the reverse of this conversion was applied in the synthesis of complex [Cr(CNCCl2)(CO)5][AlCl4] by y-abstraction of a chloride substituent from the trichloromethylisocyanide ligand in Cr(CNCCl3)(CO)5 (43).

The a-thioxamides (16) also undergo abstraction of y-H, to give /3-lactams, on irradiation in solution. Thiones, under similar conditions, suffer abstraction of <5-H, and the preferred y-abstraction with the thioamides has tentatively been attributed to an electron transfer from the amide nitrogen to the excited thio-carbonyl group preceding the shift of the proton. cv-Oxothioamides are inert to irradiation. ...
