| titleOfInvention | Process for the catalytic preparation of condensation products of formaldehyde |
| abstract | In the process, formaldehyde or formaldehyde-yielding compounds are reacted in the presence of mesoionic catalysts of the formula I <IMAGE> in which X represents a nitrogen atom or a group CR<3>, Y represents a sulphur or selenium atom or a group NR<4>, and in which the radicals R<1>, R<2> and R<3> are identical or different and represent aliphatic groups having 1 to 30 carbon atoms, optionally substituted aryl groups, optionally substituted aralkyl groups and/or optionally substituted heteroaryl groups, the radical R<4> represents an aliphatic group having 1 to 30 carbon atoms, an optionally substituted aryl group, an optionally substituted aralkyl group or an optionally substituted heteroaryl group, or in which the radical R<2>, together with the radical R<4>, forms a C2- to C5-alkylene or alkenylene bridge or a C6- to C14-arylene bridge, and in which the radical R<5> represents hydrogen, the hydroxymethylene group -CH2OH or the hydroxyhydroxymethylenemethylidine group -CH(OH)(CH2OH). |
