Abstract

Selected acyclic and cyclic phosphites (RO)2PX (1-5) were reacted with activated ketones (CF3)2CO (6) and Z-CF3C(O)CH=C(OH)CF3 (7a) / E-CF3C(O)CH=C(OSiMe3)CF3 (7b) in order to study the influence of R and X on the product formation. A new type of insertion, a 1,4 group shift and cyclo-addition reactions yielding five membered rings and bicyclic fused systems were observed. In most cases phosphonates and their λ5[sgrave]5 P derivatives were obtained. The ketones in question can be considered versatile reactants in phosphorus chemistry.
