Abstract: | In this paper,some preliminary results of the action of triethylamine on the re-action between dimethyl 2-phenyl-furane-3,4-dicarboxylate(2)and phenylmagnesiumbromides(3a-c)are reported. It was found that in the presence of triethylalnine, methyl 2-phenyl-4-benzoylfu-rane-3-carboxylates(la-c),and some-times also 2-phenl-3,4-dibenzoylfurane(4a)were formed.And, if no trietliylamine was added, methyl 2-phenyl-4-diphenyl-hydro-xymethyl-3-carboxylate(5a)was mainly formed. |
