Abstract
The preparation and the use in olefin synthesis of two 5-membered cyclic phosphonates, 2- carbethoxy-methyl 4, 5-dimethyle-2-oxo-1, 3, 2-dioxaphospholane (4b) and 2-cyanomethyl- 4, 5-dimethyl-2-oxo-1, 3, 2-diox-aphospholane (4c) and the 6-membered phosphonates, 2- carbalkoxymethyl-5, 5-dimethyl-2-oxo-1, 3, 2-diox-aphosphorinanes (5a and 5b) and 2- cyanomethyl-5, 5-dimethyl-2-oxo-1, 3, 2-dioxaphosphorinane (5c) are described. ...
