โœฆ Synopsis

In accord with stereoelectronic considerations there is a good correlation between the relative rates, regiochemistry, and stereochemistry of ring closure of w-alkenyl radicals, and the strain energies of transition structures determined by force field calculations. Theoretical studies1 of the ring closure of w-alkenyl radicals have met with only limited success. Thus, MINK)/3 calculations1 give activation energies considerably larger than those obtained experimentally2 and fail to predict the observed degree of preference for zcyclisation of 5-hexenyl and 6-heptenyl radicals.

The direct photolysis of cyclopentyl-type nitrites allows to detection, by EPR spectroscopy, the corresponding &valerolactam-l-oxyl type radical, owing to a ring expansion process as reported for steroidal 17-nitrites. For the formation of these radicals a 1,6 exo ring closure process of the interme
