The intramolecular addition of a radical to an unsaturated bond is an important synthetic
strategy for the formation of rings.'It is notable that the Mexenyl radical cyclixes preferentially …

Rate constant data and Arrhenius parameters have been determined for a series of
substituted hexenyl radicals of differing electronic and steric demand. Electron-withdrawing …

Alkoxyiminyl radicals, generated by photolysis of N-bromo imidates, undergo exo-1, 5 and
exo-1, 6 cyclization onto olefins on the O-alkyl side chains giving good yields of 4, 5 …

Calculations of the activation energy of cyclization of α-sulfenyl-, α-sulfinyl-, and α-sulfonyl-5-
hexenyl radicals and their respective 5-methyl-5-hexenyl counterparts at the G3MP2B3 level …

The kinetics of the radical cyclizations of acylsilanes is probed by the construction of an
intramolecular competition system. In this system, known rate constants of olefin cyclizations …

Rate constants have been determined at 37 C forthe ring opening of a variety of alkyl-
