Abstract

Abstract Ethyl 3-(2-pyridyl) propionate formation results from irradiation of 3-(2-pyridyl) propanal diethylacetal in acetonitrile. This photoreaction is unique to the heteroaromatic pyridine and only occurs in acetonitrile. A minor product, 1-aza-2-methyl-3-(2-ethanal diethylacetal)-4-ethoxycycloocta-1, 3, 5, 7-tetraene, is also obtained. The irradiation of 2- methyl-6-(2-pyridyl)-2-pentene in the presence of various sensitizers results in addition to ...
