Method for the preparation of tris (dimethylamino) methane |
| abstract |
A method for the methylenation of catechols via the reaction of catechols with methylene chloride in the presence of selected strong bases is described. This process has wide applicability in the field of synthetic organic chemistry, especially in natural product syntheses. |
