Bis-phosphite ligands of formula (I); carbonylation reactions using gp. VIII transition metal complexes with (I); Rh complexes with (I); and gp. VIII transition metal complex hydroformylation catalytic precursor compsns. comprising solubilised gp.VIII transition metal - (I) complex, organic solvent and free (I); are new. (where each Ar = opt. substd. aryl(ene); W = alkylene, -Ar- or -Ar-(CH2)y-(Q)n-(CH2)y-Ar-; each y = 0 or 1; each Q = -CR1R2-, -O-, -S-, -NR3-, -SiR4R5- or -CO-; R1 and R2 each = H, 1-12C alkyl, phenyl, tolyl or anisyl; R3, R4 and R5 each = H or Me; each n = O or 1; and each Z = opt. substd. alkyl, aryl, alkaryl, aralkyl or alicyclic). |
