IMPROVED LITHIUM AND AMINE DISSOLVING METAL REDUCTION |
摘要 |
The invention is directed to a process for reducing or reductively cleaving an organic compound susceptible to dissolving metal reduction comprising exposing the organic compound to a solution of lithium in a polyamine including at leat two amino groups, selected from the group consisting of primary and secondary amino groups and mixtures thereof, e.g. ethylenediamine and R-NH2, optionally containing a lower alkyl alcohol, wherein R is chosen from the group consisting of ethyl, propyl, and butyl, including all straight and branched chain isomers thereof, for a time sufficient to effect reduction.
