| 摘要 |
A composition comprising a complex of a Cu(II) salt formed from copper or a copper salt, an organosilicon compound having at least one Si-bonded group which include 2 amino nitrogens which may enter into a heterocyclic ring structure with Cu and 2 to 5 carbon atoms linking the N atoms, and water in the presence of oxygen, is useful as a catalyst for oxidative coupling reactions of certain silicon compounds. Formulations comprising up to 5 parts of the above composition and 100 parts of either arylolsilicon compounds or arylcyanophenylacetylsilicon compounds are particularly claimed.
