Typical bimolecular photoinitiators (PIs) for radical polymerization of acrylates show only poor photoreactivity because of the undesired effect of back electron transfer. To overcome this limitation, PIs consisting of a benzaldoxime ester and various sensitizers based on aromatic ketones were introduced. The core of the photoinduced reactivity was established by laser flash photolysis, photo-CIDNP, and EPR experiments at short time scales. According to these results, the primarily formed iminyl radicals are not particularly active. The polymerization is predominantly initiated by C-centered radicals. Photo-DSC experiments show reactivities comparable to that of classical monomolecular type I PIs like Darocur 1173.

A facile zinc-mediated Barbier-type allylation of aromatic aldoxime esters, producing the corresponding protected homoallylic hydroxylamines, which are readily converted into homoallylic hydroxamic acids, is described.
EFFETS MICELLAIRES SUR LA BASICITE ET LA REACTIVITE DE NUCLEOPHILES α AROMATIQUES

The oximation of p-nitrophenylacetate by benzaldoximates in aqueous solution is catalyzed by CTAB micelles.The catalysis is more effective when the base strength of the oximate decreases; the reactivity of benzaldoximates is not dependent on their basicity.Our data may be interpreted in terms of orbital-controlled reactions, with interactions between both the n and ? occupied orbitals of the oximates and the LUMO of the acetate.
