Crystal and molecular structures of two sulfonium ylides: Influence of secondary S...O interactions on the molecular conformation and packing
摘要:
Results are reported of an x-ray structure study of two sulfonium ylides formed by reaction of dimethylacetylenedicarboxylate with DMSO. It is demonstrated that one of these forms inter- and the other intramolecular secondary S...O interactions. In the first case they affect the molecular packing in the crystal; in the second, the molecular conformation.
