B2

Benzo[e][1,3,2]dioxaphosphorin-4-one derivatives (I) are new. New benzo[e][1,3,2]dioxaphosphorin-4-one derivatives are given by the formula (I): [Image] R : optionally substituted 1-50C aliphatic, alicyclic, aromatic, heteroaromatic, aliphatic-alicyclic, aliphatic-aromatic, heterocyclic or aliphatic-heterocyclic group; R 1>-R 4>H, R, halo, CF 3, CH 2(CF 2) jCF 3, OR 9>, COR 9>, COOR 9>, COOM, SR 9>, SO 2R 9>, SOR 9>, SO 3R 9>, SO 3M, SO 2NR 9>R 10>, NR 9>R 10> or N=CR 9>R 10>, or adjacent pairs can form an optionally substituted fused aromatic, heteroaromatic, aliphatic, aromatic-aliphatic or heteroaromatic-aliphatic ring system; R 9>, R 10>H or optionally substituted 1-25C aliphatic or aromatic hydrocarbyl; M : alkali(ne earth) metal, ammonium or phosphonium; k : 0 or 1. Provided that: (a) R is not alkyl, aryl, aralkyl, alkenyl or cycloalkyl when R 1>-R 4> are H and k = 0; and (b) R is not alkyl or aryl when R 1>-R 4> are H and k = 1. Independent claims are also included for: (1) group 4-10 metal complexes of compounds (I) as defined above but without provisos (a) and (b); (2) a process for hydroformylating olefins, comprising reacting a monoolefin with carbon monoxide and hydrogen in the presence of a compound (I) or a complex as in (1); (3) a process for preparing compounds (I); (4) a process for preparing the complexes of (1), comprising reacting a group 4-10 metal or metal compound with (I).
