✦ Synopsis

Abstract

Irradiation of 3‐phenyl‐(4), 2‐methyl‐3‐phenyl‐(8), and 2,3‐diphenyl‐2__H__‐azirine (10), in benzene solution in the presence of aldehydes, yields the corresponding aryl‐3‐oxazolines. Photochemical reaction of 4 and 10 with carbon dioxide leads to the formation of 4‐phenyl‐ (15) and 2,4‐diphenyl‐3‐oxazolin‐5‐one (16), respectively.

## Abstract Solutions of the title compounds R‐Ti(OR′)~3~ (**1**) are generally available from organolithium (or magnesium) derivatives according to equation 1. It is shown (__Table 1__) that some heterosubstituted organotitanium compounds are more stable thermally than their lithium counterparts.
