摘要
Electron-deficient borole compounds exhibit a pronounced Lewis acidity that is enhanced due to their antiaromatic character so that even weak donors datively coordinate to form Lewis acid-base adducts. This contribution presents the synthesis and structural characterization of Lewis acid-base adducts formed by the reaction of 1-mesityl-2,3,4,5-tetraphen-ylborole and 4-picoline as well as 1-chloro-2,3,4,5-tetraphenylborole with various donors. The new compounds are characterized by means of multinuclear NMR spectroscopy and single-crystal X-ray diffraction techniques and compared to related systems.
