Abstract: Cpds. of formula (I) (where each R is H (prefd.) or an aliphatic gp.) are useful as inters. for dyes, pesticides and plastics stabilisers, are themselves useful as stabilisers (e.g. for poly-olefins and polyamides), and are specific solvents in the molten state. They can be prepd., e.g., by reducing the corresp. butan-2-one.

Abstract: Isopiperitenol (I), which can be hydrogenated to menthol and is an inter for synthesis of tetrahydrocannabinols, is prepd by heating 3-Me-2-butene-1-ol with 3,3-dimethylacrolein for >=1 hr, at 165-300 degrees C, in the presence of 0.01-5 wt. % w.r.t. sum of reaction components, of an acid as catalyst, in the liq. phase, whereby citral formed initially is cyclised to (I). Process is a modification of higher mol wt alpha, beta-unsatd. aldehyde prepn disclosed in DT 2157035, by reacting an allyl alcohol with an alpha, beta-unsatd aldehyde.

Abstract: New cpds. (I) are of formulae XOOCR3, XNHCOR3, XNHCONHR4NHCONHX and XNHCO-(R5)n-CONHX, (where gp. X is of formula (II) and R1 are H (pref.) or aliphatic gps; R3-5 are aliphatic, cycloaliphatic, arylaliphatic or aromatic gps; and n = 0 or 1). (I) esters are prepd. by reacting the alcohol XOH with the carboxylic acid R3COOH or the corresponding acid halide or anhydride at 10-170 degrees C, pref. 20-90 degrees C. The amide, bisamide or bisurea is formed by reacting the amine XNH2 with derivs of the carboxylic acids R3COOH or HOOC-(R5)n COOH, or with the bi-isocyanate OCN-R4-NCO respectively. The cpds. are used as starting materials for dyestuffs, pesticides, plastics and perfume compsns. or as stabilizers or antioxidants for organic materials, e.g. polymers.
