DEFINITION

Classification: 556/469

(under subclass 466) Processes in which there is an interchange of radicals between silicon atom, i.e., a shift of a radical, unchanged, from one silicon atom to another silicon atom.

(1) Note. Included in this subclass are the processes of redistribution, disproportionation, transesterification, etc., e.g., [figure]

(2) Note. This interchange may occur when plural molecules of the same silicon compound are acted upon in such a manner as to produce two different silicon compounds via molecular redistribution, e.g., [figure]
