Abstract
The reaction of pyrocatechol chlorophosphite with N-trimethylsilylacetamide gave 2-acetamido-4,5-benzo-1,3,2-dioxaphospholane. The reaction of this product with hexamethyldisilazane leads to 2-trimethylsiloxy-4,5-benzo-1,3,2-dioxaphospholane, while its reactions with diethylamine, trimethylsilyldiethylamine, and bis(dimethylamino)methane give 2-dialkylamino-4,5-benzo-1,3,2-dioxaphospholanes.
