Novel organoborane compound type from the reaction of diphenylbromoborane with di-isopropylcarbamoyl-lithium

Abstract

Addition of diphenylbromoborane to di-isopropylcarbamoyl-lithium at low temperature followed by warming to ambient, and passage through silica gives 5-(di-isopropyliminio)-2,2,4,4-tetraphenyl-2,4-diborata-1-oxa-3-oxoniacyclopentane (2).
