Abstract
A process for the production of (1) an ether or (2) a second amine comprises reacting an activated olefin with respectively an alcohol or first amine in the presence of a catalyst which is either (a) an amidine or (b) a Lewis base and epoxide. The same catalyst may also be used to carry out the reverse reaction in which an activated olefin and an alcohol or first amine are produced from the appropriate ether or second amine.
Claims7
A process for the production of a second amine, said second amine having the formula ##STR6## where R.sup.1, R.sup.2 and R are hydrogen, X or hydrocarbyl radicals, R.sup.4 and R.sup.5 are hydrocarbyl radicals or hydrogen, and
- X is an electron withdrawing group,
- which process comprises reacting an activated olefin with a first amine,
- said activated olefin being one which can undergo the Michael Reaction, and said first amine being selected from the group consisting of methylamine, ethylamine, propylamine, dimethylamine, diethylamine and ammonia, in the presence of an effective amount of a catalyst, characterised in that the catalyst is
- (a) an amidine, or
- (b) a Lewis base and epoxide.
