A hypothesis for conformational restriction in complexes of formyl compounds with boron Lewis acids. Experimental evidence for formyl CH--O and CH--F hydrogen bonds

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. Graphic
