Abstract

Abstract The photochemistry of the α-bis (methoxyimino) alkanes 1–5 and the, structurally related, conjugated dihydro (methoxyimino) isoxazoles 6 and 7 was studied. Triplet- photosensitized irradiation of 1–7 leads only to stepwise EZ isomerization. Photostationary- state (pss) ratios for 1, 6 and 7 are reported for the various applied triplet sensitizers. Direct irradiation with 254 nm leads to both EZ isomerization (which is the dominant reaction) ...
