Claims
- 1. A nitrogen heterocycle substituted alkyl diaryl phosphine rhodium carbonyl hydride complex catalyst of the formula ##STR67## wherein Ar is an aryl group containing from 6 to 10 carbon atoms;
- Q is a divalent organic radical selected from an alkylene radical and an alkylene radical the carbon chain of which is interrupted at least one ether oxygen or phenylene group wherein said alkylene radical contains from 1 to 30 carbon atoms;
- R represents a divalent organic radical selected from the group consisting of ##STR68## which together with the nitrogen atom forms a heterocyclic nitrogen-containing ring wherein R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are hydrocarbyl radicals such that said heterocyclic ring contains from 5 to 6 atoms; and g is 2 or 3.
- 2. A catalyst complex of claim 1 wherein Ar is phenyl and Q is (CH.sub.2).sub.2 or (CH.sub.2).sub.3.
