摘要

Benzo- and naphtho-bisphosphites and their complexes with sub-Group 4-8 metals are claimed. Benzo- and naphtho-bisphosphites of formulae (I) - (IV) and their complexes with sub-Group 4-8 metals are claimed. R<1> - R<6> = H, 1-50C aliphatic, alicyclic, aliphatic-alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic, aromatic-aromatic or aliphatic-aromatic hydrocarbons, F, Cl, Br, I, CF3, OR<7>, COR<7>, CO2R<7>, CO2M, SR<7>, SO2R<7>, SOR<7>, SO3R<7>, SO3M, SO2NR<7>R<8>, NR<7>R<8>, N:CR<7>R<8> or NH2 with R<1> - R<4> and R<1> - R<6> optionally covalently bonded to each other; R<7> and R<8> = H or 1-25C optionally substituted aliphatic or aromatic hydrocarbons; M = alkali(ne earth) metal, ammonium or phosphonium; Q = divalent 1-50C aliphatic, alicyclic, aliphatic-alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic or aliphatic-aromatic hydrocarbon; W and X = 1-50C aliphatic, alicyclic, aliphatic-alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic, aromatic-aromatic or aliphatic-aromatic hydrocarbons which are optionally covalently bonded to each other.
