B01J2231/342 - CPC Classification

Classification description:

Catalytic reactions performed with catalysts classified in; Addition reactions at carbon centres, i.e. to either C-C or C-X multiple bonds; Other additions, e.g. Monsanto-type carbonylations, addition to 1,2-C=X or 1,2-C-X triplebonds, additions to 1,4-C=C-C=X or 1,4-C=-C-X triple bonds with X, e.g. O, S, NH/N 1,2-additions, e.g. aldol or Knoevenagel condensations Aldol type reactions, i.e. nucleophilic addition of C-H acidic compounds, their R3Si- or metal complex analogues, to aldehydes or ketones
