Hx. Lin et al., STUDIES ON THE REACTION AND MECHANISM OF TETRACHLOROMETHANE WITH MAGNESIUM - A NOVEL METHOD FOR THE GENERATION OF DICHLOROCARBENE, Gaodeng xuexiao huaxue xuebao, 16(10), 1995, pp. 1572-1574
The reaction oi tetrachloromethane with magnesium under general Grigna
rd reaction condition was studied, It is found for the first time to p
roduce dichlorocarbene which is trapped with different olefins to prep
are gem-dichlorocyclopropane derivatives in good yields. The reaction
having the advantages of easy work-up,mild reaction condition and high
yield is a convenient method for the generation of dichlorocarbene, A
possible mechanism (single electron transfer,SET) was proposed, The s
olvent effects on the reaction were studied.
