摘要：

X-Ray crystallographic analysis of six complexes of formyl compounds with B-F or B-O containing boron Lewis acids reveals in every case a geometric preference for a conformation in which the formyl group and the B-F or B-O bond are coplanar, or nearly so. Copyright (C) 1996 Elsevier Science Ltd
