• 中文摘要： Because the extensive d.pi.-p.pi. interaction between silicon and oxygen, the monomeric five-membered ring products, (methyl-1,2-phenylenedioxy)diorganosilanes, rather than dimers were synthesized from methylcatechols and dichlorodiorganosilanes. In addition to the five-membered ring products, the more stable seven-membered-ring cyclodisiloxanes were found. From the X-ray diffraction data of these seven-membered-ring disiloxanes, the latter were found to be free of ring strain and to have better conjugation than the five-membered ring species in the Si-O-C(Ar) moiety of the molecules.
