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.
本发明提供了在使用醚烷基化剂烷基化含
氨基或酰胺基化合物时使用B族金属氧化物烷基化催化剂的方法。因此,在B族金属氧化物烷基化催化剂的存在下,可以通过与非张力环状醚反应来进行
氨基和酰胺的N,N-环状烷基化,最好使用IV-B族金属氧化物如
二氧化钛。
