    Abstract: 2-( omega -alkoxycarbonyl alkanoyl)-4-butanolide can be produced unexpectedly with a high selectivity and yield through condensation reaction of gamma -butyrolactone with a highly available, lo omega -price dicarboxylate as represented by the following general formula: ROOC(CH2)nCOOR (where n denotes an integer of 7-13, and R denotes an alkyl group or an alkenyl group). Furthermore, a long-chain omega -hydroxycarboxylic acid can be produced by subjecting 2-( omega -alkoxycarbonyl alkanoyl)-4-butanolide to hydrolysis and decarboxylation and reducing the carbonyl groups in the resultant product into methylene groups.

    Abstract: A platinum(II) complex is represented by the general formula (A), in which R1 represents a hydrocarbon radical having 1 to 10 carbon atoms, R2 and R3 each represent a hydrogen atom or a hydrocarbon radical of 1 to 10 carbon atoms, or R2 and R3, together, may form -(CH2)4- or -(CH2)5-, and X R2 and R3, together, may form -(CH2)4- or -(CH2)5-, and X and Y each represent an ammonia molecule or a monodentate and Y each represent an ammonia molecule or a monodentate amine having 1 to 7 carbon atoms or X and Y, together, amine having 1 to 7 carbon atoms or X and Y, together, may form a bidentate diamine having 2 to 10 carbon atoms. The compounds are useful for treating tumors.

    Abstract: 1,150,848. Condensation catalysts. TOYO RAYON K.K. 3 Oct., 1967 [4 Oct., 1966], No. 44905/67. Heading B1E [Also in Division C5] Catalysts used in the co-dimerisation of ethylene and a conjugated diene (see Division C5) comprise:- a) a cobalt salt (including inorganic and organic salts, and chelate compounds), b) a sulphur-containing tertiary phosphine having one 'of the formulae where the R's are organic groups and n is 2 or 3, and c) an organo-aluminium compound of formula where R 4 and R 5 are C 1-10 hydrocarbon groups and X is halogen or a C 1 _ 10 hydrocarbon group.
