摘要:
The invention provides the use of a B-subgroup metal oxide alkylation catalyst in alkylating an amino or amido group-containing compound using an ether alkylation agent. Thus, amines and amides may be N,N-cyclodialkylated by reaction with an unstrained cyclic ether in the presence of a B-subgroup metal oxide alkylation catalyst, preferably a Group IV-B metal oxide such as titanium dioxide.
