    Abstract: omega -Formylalkanecarboxylic esters are prepared by hydroformylation of alkenecarboxylic esters with carbon monoxide and hydrogen at elevated temperature and under elevated pressure in the presence of cobalt carbonyl complexes, in which alpha , beta -unsaturated alkenecarboxylic esters are hydroformylated in the presence of 0.01 to 1 mol% of cobalt carbonyl complexes, calculated as cobalt, while maintaining a conversion of alpha , beta -unsaturated alkenecarboxylic esters of 10 to 70 %.

    Abstract: Preparation of phosphabenzene compounds (A) by reacting the corresponding pyrilium salt (III) with phosphine, optionally in presence of solvent but without addition of acid catalyst or base. (III) and phosphine are contacted at about 0 degrees C then reacted at 0-200 degrees C at pressure over 1 bar. (A) have formulae (I) or (II); R -R = hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR, SR, 1-12C alkyl, 6-12C aryl, 7-12C aralkyl or alkaryl, or 3-6C heterocyclylalkyl with 1-3 heteroatoms, optionally substituted by the above groups, or two or more R groups together form a fused aliphatic ring; M = hydrogen, ammonium or alkali metal; X = anion; R = hydrogen or 1-6C alkyl; W = bridge comprising covalent bond, oxygen, sulfur, amino, di(1-6C)alkylsilyl or 1-16C residue that includes one or more linked cyclic or aromatic nuclei and optionally interrupted by 1-3 heteroatoms, and each o- or m-position on the phosphabenzene ring that is not bound to the bridge may be substituted by R -R .

    Abstract: Olefinically unsaturated compounds are hydroformylated in an organic reaction medium with the aid of rhodium complex catalysts which are soluble in the reaction medium by performing the reaction in the presence of water-insoluble rhodium complex catalysts and also in the presence of arylthiols of the general formula I Ar-SH I where Ar is substituted or unsubstituted aryl.

    Abstract: Prodn. of carbonyl cpds. (I) comprises catalytic isomerisation of allyl alcohol deriv. (II) in presence of a Rh cpd. at 80-180 deg. C. The new features are that (1) reaction is in a tert. phosphine or phosphite; (2) a carrier gas is passed through the reaction mixt. and (3) (I) is sepd. from the withdrawn gas stream by cooling. Specifically, (I) and (II) are of formulae R3R4CH.CHR2.COR1 and R3R4C=CR2-C(OH)HR1 (R1 and R4 = H or Me; or together a 3-6C, aliphatic or olefinic chain; R2 = H, Me or alkoxycarbonyl; R3 = H, Me or CH2OH).

    Abstract: Prodn. of 2(5H)- furanones of formula (I) comprises reacting 3-formylcarboxylic acid or esters O = C(H)-CH(R1)-C(H)(R2) 0 = C(H)-C(H)(R1)-C(H)(R2)-(O)C-OR3 (II) in presence of acid catalyst at 100-450 deg. C. R1 and R2 = H, 1-6C alkyl, 5-6C cycloalkyl, 7-12C aralkyl or aryl; R3 = H, 1-12C alkyl, 5-6C cycloalkyl, 7-12C aralkyl or aryl. Acid catalysts are acidic oxides of B, AR, Si, P or metals of sub-groups IV-VI,or natural or synthetic zeolites. The catalysts are SiO2, Al2O3, B2O3, TiO2, V2O5, Cr2O6, or X Y or pentasil type zeolites. In (II), R1 and R2 are 1-6C alkyl and R3 = 1-12C alkyl. Reaction is at 200-350 deg. C and 1-50 (pref. 1-5) bar, and lactonisation is in presence of water and/or 1-4C alcohol. Where a heterogeneous catalyst is used, it is 0.5-20 wt. % on (II) for liq. phase reaction, or 0.1-10 (esp. 0.1-5)g (II) is used per g catalyst per hr., for gas phase reaction. Reaction is opt. in presence of 0.1-50 (pref. 0.5-20) moles solvent per mole (II).
