摘要：
Reactions with aryl halides (ArX) of preparations obtained in diethyl ether from an R2Mg compound and a cryptand, an alkali-metal alkoxide, or tetrabutylammonium bromide lead to ArH and ArR. ArH results from magnesium-halogen exchange, and ArR results from aryne formation. Reactions of similar preparations with pyridine lead to formation of larger amounts of substitution product, and those with 2-cyclohexen-1-one to larger amounts of 1,4-addition product, than do reactions of R2Mg alone.
