摘要

This work was done in an effort to obtain polybromo and polynitro compounds from piperonal for use in testing the effect of negative substituents in the formation of stereoisomeric benzaldoxime derivatives. Previously Orr, Robinson and william^,^ and later Parij~,~ found that treatment of an acetic acid solution of piperonal with bromine gave a mixture of 6-bromopiperonal and 4, 5-dibromocatechol methylene ether, which involved ...
