[origin: DE19654908A1] A catalyst (I) contains rhodium and a 2,2'-bisaryl bis-ether of formula (II) (in which R1, R2, R3 = hydrogen, 1-4 carbon alkyl or alkoxy or 2-4 C alkenyl; or C(R1)-C(R2) = a 6 C ring; m, n = 0 or 1; (m + n) = 1 or 2; R = phenyl or naphthyl, optionally mono-substituted by 1-4 C alkyl, amino or 2-8 C dialkylamino. Aldehydes production is also claimed.
