Organic Derivatives of Boron. Part I. Synthesis by Alcohol Interchange Technique

The reactions of ethyl borate with butanols (n & tert.), ethylene glycol, catechol, salicylic acid, and anthranilic acid have been studied in different stoichiometric ratios in refluxing benzene. The alcohol produced has been removed azeotropi­cally with benzene; the advantages of this technique have been discussed. The following compounds have been synthesised by the above procedure : ethyl dibutyltborate, ethyl ethylene-borate, diethylene ethylenedi-(borate), ethyl and butylt o-phenyleneborates, tri-o-phenylene-bis-borate, borosalicylic acid, ethoxyboron anthranilate
