Autor: Cheng-Kwang Chen, Chao-Shiuan Liu, Yi-Ming Pai

Publikováno v: Journal of Organometallic Chemistry. 226:21-34

The cocondensation reactions of difluorosilylene with cyclopentene and cyclohexa-1,3-diene have been studied. Several new organosilacyclic compounds were synthesized and their structures characterized. In all but one case the products contain SiF2SiF

Silicon-29 NMR studies of polymethylhydrosiloxanes: Spin-lattice relaxation time (T1) measurements

Autor: Yi-Ming Pai, Kenneth L. Servis, William P. Weber

Publikováno v: Journal of Organometallic Chemistry. 288:269-273

29Si NMR spectra of polymethylhydrosiloxanes, Me3SiO[MeHSiO]nSiMe3 from n = 3 to 8 and 35, have been determined. Both chemical shifts and spin-lattice relaxation times (T1) have been measured. The stereochemistry at the adjacent chiral MeHSiO unit in

Deuterium isotope effects on silicon-29 chemical shifts

Autor: William P. Weber, Fabienne Berchier, Kenneth L. Servis, Yi-Ming Pai

Publikováno v: Magnetic Resonance in Chemistry. 24:679-680

The deuterium isotope effects on the 29Si chemical shifts in several organosilanes and siloxanes have been determined. For silanes, the one-bond effects are approximately −0.2 ppm per deuterium and follow an additivity relationship. The two-bond ef
