In specified examples polyformaldehyde is prepared from formaldehyde using ethylzinc diphenylphosphine, or butylzinc diphenylamine as catalyst; and polyacetaldehyde is prepared from acetaldehyde using ethylzinc diphenylamine, N-ethylzinc acetanilde or phenylzinc diphenylphosphine as catalyst.ALSO:The invention comprises organo-zinc compounds of formula RZnXYY1; wherein R is alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl, or aralkyl, the longest carbon chain in the radical not having more than 12 carbon atoms and the radical being attached directly to the zinc atom through a carbon atom; X is trivalent nitrogen, phosphorus or arsenic; Y and Y1, which may be the same or different, are alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl or groups containing carbonyl or thiocarbonyl radicals.  These compounds are prepared by reacting R2Zn with a compound HXYY1 preferably in equimolar amounts. When X is nitrogen, Y and/or Y1 may contain a >C=O or >C=S group with one bond attached to this nitrogen atom and the other to a nitrogen or phosphorus atom.  This latter atom has two further radicals attached to it. Examples of such compounds are EtZnNPhCONPh2 and EtZnNPhCSPPh2.  These compounds may be prepared by reacting a compound of formula RZnNYY1 with an aliphatic or aromatic isocyanate or isothiocyanate.  The compounds of the invention may be used as catalysts in the polymerization of carbonyl compounds and in the trimerization of isocyanates.  In specified examples trimethylisocyanate is prepared from methyl isocyanate using N-ethylzinc-N,N1,N1-triphenylurea or ethylzincdiphenylarsine; triphenylisocyanate is prepared from phenylisocyanate using ethylzincdiphenylphosphine as catalyst.
