摘要

Abstract The reactions of tetrabutylammonium aci-nitronates with p-dinitrobenzene in dimethyl sulfoxide, benzene or acetone proceed far more rapidly than the reactions of the corresponding lithium salts and give, in unhindered cases, good yields of C-arylates, eg p-(1- methyl-1-nitroethyl) nitrobenzene (in 73-89% yields) and p-nitro (l, 3, 3-trimethyl-1- nitrobuty1) benene (in 70% yield). With more sterically hindered nitronates, O-arylation ...
