Phenyl alkyl ketones were photo-irradiated in the presence of Cr(VI) or Mn(VII) oxidants to yield 1,4-dicarbonyl compounds regiospecifically while 2-octanone gave a regioisomeric mixture of 2,5-, 2,6-, and 2,7-octadiones.
在Cr(VI)或Mn(VII)氧化剂存在下,对苯烷基酮进行光照射,以产生区域特异性的1,4-二羰基化合物,而2-辛酮则生成2,5,2,6-和6,5,5-三氯乙烷的区域异构体混合物。 2,7-辛二酮。
