A general method for exhaustively alkylating amines to quartemary camoniian aompoimds at room temperature makes use of the sterlcally hindered base 1,2,2,6,6-pentamethyl piperidine. Cyclic or acylic higher olefins may be aminomethylated with CO, H2O, and a secondary amine in the presence of rhodium oxide (and/or iron pentacarbonyl). ...
