Abstract

In the hydrolysis reaction of dichlorosilanes having an intramolecular coordinating atom, dcisiloxane-1,3-diols, [(OH){o-(CH₃) ₂NCH₂-C₆H₄}RSi]₂ O(R=CH₂=CH (1), C₆H₅ (2), o-(CH₃)₂NCH₂C₆H₄ (3), Me (4)), were obtained in high yields. The results of the crystal structure analyses of meso-2, rac-2a, rac-2b and 3 are reported. They showed strong intramolecular hydrogen bondings between the hydroxy group and the nitrogen atom. We have also found that the diastereomeric isomerization of meso-2 to rac-2 in CDCl₃ solvent containing moisture occurred to result in the 55:45 equilibrium mixtures of the isomers and vice versa.
