O-ACYL-α-OXOOXIMES AND RELATED COMPOUNDS. CHEMISTRY, PHOTOCHEMISTRY, AND USE AS PHOTOINITIATORS FOR RADICAL POLYMERIZATIONS

The present paper reviews the photochemistry of O-acyl- and O-alkyloximes both with and without an α-oxo group. Special attention is paid to the application of O-acyl-α-oxooximes as photoinitiators for the UV polymerization of unsaturated monomers or as additives in photoinitiators systems sensitive to visible light. In addition, present available information on their ground states, including synthesis and synthetic applications, spectroscopic properties, E/Z-configurational analysis, conformational analysis and thermal stability, is also reviewed.
