## Abstract A value of the enthalpy of formation of the phenoxy radical in the gas phase, ฮ__H__ยฐ~,298K~ (ฯOยท, g) = 11.4 ยฑ 2.0 kcal/mol, has been obtained from the kinetic study of the unimolecular decompositions of phenyl ethyl ether, phenyl allyl ether, and benzyl methyl etherTrivial names for et
Allylation and crotylation reactions of 2,3-anti-B-hydroxy-a-methyl aldehydes 10 and 11 with ally1 and crotyltrifluorosilanes 2, 8 and 9 proceed with high selectivity via the bicyclic chelated transition states 3 and 30. In contrast, analogous allylation and crotylation reactions of the 2,3-syn-l3-h
