The title compounds were prepared by the Erlenmeyer synthesis and irradiated with or without a Pyrex filter using 450 W medium pressure mercury arc lamp. Cis-trans isomerization was the major reaction under pyrex filtered condition, whereas irradiation without a Pyrex filter resulted in decarbonylation, followed by trapping of the ketenimine intermediate by protic solvents.
通过Erlenmeyer合成法制备标题化合物,并使用450 W中压汞弧灯在有或没有Pyrex滤光片的情况下进行辐照。顺式-反式异构化是在耐热玻璃纤维过滤条件下的主要反应,而没有使用耐热玻璃纤维过滤器的照射导致脱羰基化,随后质子溶剂捕获酮亚胺中间体。
