Geminal 2J(29Si-O-29Si) Couplings in Oligosiloxanes and Their Relation to Direct 1J(29Si-13C) Couplings
Original language description
Relationships are found between 79 measured 2J(29Si-O-29Si) couplings in oligosiloxanes and 29Si chemical shifts, number of oxygenous substituents and 1J(29Si-13C) couplings. In selected compounds the signs of the 2J couplings are positive, it is arguedthat all the 2J(29Si-O-29Si) couplings are positive. Density functional calculations failed to reproduce the signs and trends in the couplings.
