摘要:
This invention aims to provide a compound that is useful as a cocatalyst for the polymerization reaction of olefins, dienes, and acetylenes. According to this invention, it is possible to provide a useful and highly active cocatalyst for the polymerization reaction of olefins, dienes, and acetylenes, represented by the following formula (1): [The definitions of the symbols in the formula are as described in the specification.] containing a fluorine-containing alkylammonium borate compound and compositions containing it, as well as methods for their production.

Selective protection of primary amines in the presence of secondary amines and monofunctionalization of symmetric primary and secondary diamines using ethyl trifluoroacetate is described. Effective differentiation of primary, secondary and tertiary alkyl-substituted primary amines from one another by ethyl trifluoroacetate acylation is also demonstrated. These results are explained on the basis of
