    Abstract: Prodn. of trialkyl 4-phosphono-2-methyl-2-butenoate esters of formula (I) with a high E-isomer content comprises (a) reacting an alkyl 2-hydroxy-2-methyl-3-butenoate of formula (II) with PBr3 or PCl3 at 0-80 degrees C in the absence of pyridine to form a mixt. of an alkyl 4-halo-2- methyl-2-butenoate of formula (III) and an alkyl 2-halo-2-methyl-3-butenoate of formula (IV), and (b) reacting the mixt. with a trialkyl phosphite of formula (V) at 70-140 degrees C. R1, R2 = Me or Et; X = Cl or Br. Also claimed is the prodn. of (III) as in step (a) above at a temp. of 20-80 degrees C.

    Abstract: The invention comprises the dyes having the formula wherein F represents an azo or anthraquinone dye radical free from sulphonic acid groups and R represents an alkylene or arylene group. The dyes may contain as substituents in F, OH, halogen, NO2, alkyl, aryl, alkoxy, aryloxy and acylamino groups. They may be obtained by reacting one mole of an acid halide of the formula wherein Hal represents Cl or Br with at least twice the molar amount of an azo or anthraquinone dye containing a primary amino group but no SO3H groups. The anthraquinone dyes used as starting materials may be derived from anthraquinone or condensed anthraquinone derivatives such as benzanthrone, dibenzanthrone, isodibenzanthrone, pyrazolanthrone, anthrapyrimidine, anthraquinacridone, pyranthrone, indanthrone, flavanthrone and perylene tetracarboxylic-imide compounds. Examples are given for the production of dyes in which F is an anthraquinone dye or a condensed anthraquinone dye. They may be used in pastes, flush pastes, printing inks, distempers, binder colours and lakes, or incorporated in synthetic or natural macromolecular substances, or for mass coloration of fibres of acetyl cellulose, polyacrylonitrile, polyesters, polyurethanes and polyvinyl chloride, or of paper, or for colouring inorganic materials, e.g. cement.

    Abstract: Preparation of N-acyl derivatives (I) using readily available starting materials. N-acyl derivatives of formula R -C(O)N(H)C(R )X (I) are prepared by reacting, in the presence of a compound of formula R -COOH (II), a carbonic acid amide of formula R -CONH2 (III) and a glyoxalmonoacetal derivative of formula R C(O)C(OR )OR (IV). R , R = H or optionally substituted alkyl or aryl; R ,R = 1 - 12C alkyl; and X = CH(OR ) or COOR . An Independent claim is also included for a compound of formula R -C(O)N(H)C(R )C(OR )OR (V).

    Abstract: The invention comprises compounds of the formula wherein the group COX is attached at position 12 or 13 of the phthaloperinone nucleus, X is SR or preferably OR, R is H or an alkyl, cycloalkyl, aralkyl or aryl radical, and may be substituted, Y is Cl or Br, m is 0-4, n is 0 or 1. The compounds are prepared by condensing trimellitic acid or an acid derivative thereof or halogenated trimellitic acid with 1,8-diaminonaphthalene or a halogenated derivative. The phthaloperinone carboxylic acid may be esterified and/or halogenated.
