Abstract

Treatment of various cyclic phosphites (1), eg, 2-methoxy-1, 3, 2-dioxaphosphorinane (1a), 2- methoxy-5, 5-dimethyl-1, 3, 2-dioxaphosphorinane (1b) and 2-methoxy-1, 3, 2- dioxaphosphorane (1c), with haloacetones (2) gave cyclic Arbuzov products (3), cyclic Perkow products (4), cyclic methylphosphonates (5), and acyclic products (6-8). Compound 1a gave all of the products (3a, 4a, 5a, 6ag, 7ag, 8ag). However, cyclic phosphites with ...
