The main products of the photochemical reactions of methyl diazoacetate with CBrCl3 and CBr2Cl2 have been unambiguously characterized as CCl3CHBrCO2CH3 and CBrCl2 CHBrCO2CH3, respectively. These results,together with the 1H and 13C CIDNP spectra,support the formation of these products by recombination of radical pairs (Remark: Graphics omitted.) which in turn are formed by preferential attack of carbene
重氮乙酸甲酯与 CBrCl3 和 CBr2Cl2 光化学反应的主要产物分别明确地表征为 CCl3CHBrCO2CH3 和 CBrCl2 CHBrCO2CH3。这些结果与 1H 和 13C CIDNP 光谱一起支持通过自由基对的重组形成这些产物(备注:图形省略。)反过来又是由卡宾:CHCO2CH3 优先攻击溴原子形成的。
