Primary carbon radicals, generated by photolysis of acyl derivatives of -hydroxy-2-thiopyridone, exchange efficiently on diisopropyl telluride to give isopropylradicals which can in turn be trapped by radicophilic olefins.

Alkyl radicals generated from O-acyl derivatives of N-hydroxy-2-thiopyridone added onto acrylamide at room temperature to form crystalline 2-(2-pyridylsulfanyl)-car☐amides. Desulfurization of the latter by nickel boride at room temperature afforded primary amides in quantitative yield. 3-Deoxy-D-arabino-2-heptulosonic acid (DAH), its 4-epimer, and their derivatives were effectively synthesized from
The present invention concerns photopolymerisable systems comprising reactive oligomers and/or monomers having ethylenically unsaturated groups and as photoinitiator at least one hydroxamic ester of Formula (I) or (II) or (III).
