solution between room temperature and −115°C gives ether 5 as the only volatile product. Photolysis of 1 in polycrystalline (S)-2-butanol at −196° gives 5 as well as the 5 products derived from formal CH insertion of the carbene into the matrix. Tertiary alcohol 6 was formed in 15% yield and was shown to be enantiomerically pure.
在室温至-115°C之间的溶液中,二苯基重氮甲烷1在RS-2-丁醇中的光解在室温至-115°C之间产生了唯一的挥发性产物醚5。1在多晶(S)-2-丁醇中在-196°下光解产生5以及5种产物,这些产物来自卡宾从基团中正式CH插入到基体中。以15%的产率形成叔醇6,并显示其为对映体纯的。
