1,2-Oxaphospholanes |
| abstract |
2-Oxo-2-alkoxy-5-dialkylphosphono-1,2-oxaphospholanes of the formula <IMAGE> in which R1 to R7 are hydrocarbon radicals can be prepared from alpha , beta -unsaturated ketones and 2 or more moles of a dialkyl phosphite. Obviously alpha -ketophosphonates are intermediates of this reaction, as these compounds react with 1 or more moles of dialkyl phosphite in yielding the oxaphospholanes too. Both reactions are promoted by alkaline catalysts. |
