Abstract

Abstract: Reactions of the dione (1) and lactone (2) dimers of dimethylketene with a series (3- 7) of cyclic aminophosphines, alkyl phosphorodiamidites, and dialkyl phosphoramidites were studied. Essentially the same products resulted with a given trivalent phosphorus compound (3-7) and either 1 or 2, the product being a carboxamide or carboxy ester (17, X=(CH&N or CH30). With 2 and 2-dimethylamino-3-methyl-1, 3, 2-oxazaphospholane (6) ...
