Cyclic nitrile carbonate-containing compounds having the structural formula: ##STR1## wherein T is O, S, or NR''; R and R' are organic radicals; R' is hydrogen, halogen or an organic radical and R'' is hydrogen or an organic radical are prepared by reacting a cyclic nitrile carbonate-containing chloroformate having the structural formula: ##STR2## with a nucleophilic compound having the structural formula: ##STR3## wherein T, R, R', R' and R'' are as defined above, under conditions such that the TH group will react with the chloroformate group, but no reaction will occur involving either the cyclic nitrile carbonate group or the ##STR4## group. The novel compounds of the invention are useful in the preparation of crosslinkable polymers.

Cyclic nitrile carbonate-containing compounds

A process for the production of ureas by contacting at elevated temperatures and pressures in a basic solution a nitrogenous organic compound containing at least one non-cyclic group, in which a nitrogen atom is directly attached to a single carbon atom and is also attached through a double bond to an oxygen or another nitrogen atom, with carbon monoxide and with water or another nitrogenous organic compound in which the nitrogen atom is directly attached to at least one hydrogen atom, in the presence of an active amount of a catalyst selected from the group consisting of selenium, sulfur, compounds containing selenium, sulfur compounds and mixtures thereof.

Process for the manufacture of ureas

Production of oximes (and ketones) by contacting at elevated temperatures and pressures, a primary or secondary saturated aliphatic nitrocompound with carbon monoxide in the presence of a catalyst comprising metallic selenium or inorganic selenium compounds and a base.
