Abstract: Production of bis(phosphino/arsino-) compounds comprises reaction of an alkylene sulfate with alkali metal phosphine or arsine compounds. A process for the production of compounds of formula R R E-CR R -(CH2)nCR R -ER R (1) comprises reaction of an alkylene sulfate of formula (2) with an alkali compound of formula R R EM (3) and an alkali compound of formula R R EM (4); R -R = H, OH, halogen, acyl, CHO, 1-12C alkyl, 6-12C aryl, whereby R and R or R and R may not be simultaneously OH; R -R = 1-20C alkyl, 3-10C cycloalkyl, aryl or heteroaryl having up to 4 condensed aromatic rings or 7-20C aralkyl, (un)substituted; E = P, As, N; R E, R E = S; n = 0-6; M = Li, Na or K.

Abstract: The invention relates to a method for selectively producing 3-alkene acid esters by adding alkyl formates to dienes according to general reaction formula (I), wherein R1 to R6 independently from one another are hydrogen or C1-C30-alkyl, C6-C30-aryl, C7-C30-alkylaryl, C5-C12-cycloalkyl or C1-C21-alkyl-C6-C9-cycloalkyl and R7 is a C1-C30-alkyl radical, in the presence of CO with a partial pressure of at least 10 bar (1 MPa), using a catalyst containing a Pd-compound and one or more compounds of the MCln-type, whereby M has one of the following meanings: an alkaline earth metall ion with n = 2, a metallic ion of the fourth group (IV. subgroup) with n = 4, a metallic ion of the sixth group (VI. subgroup) with n = 3, 5 or 6, in the absence of an organic base containing phosphor or nitrogen.

Abstract: Ruthenium complexes of the formula I or IVwhereX, Y are anionic ligands,R is hydrogen or a substituted or unsubstituted C1-C20-alkyl radical or C6-C20-aryl radical andL1 and L2 are, independently of one another, uncharged electron donor ligands, are prepared by(a) reaction of RuX3 with L1 and L2 in an inert solvent in the presence of a reducing agent and hydrogen and(b) reaction with compounds of the formula IIwhere R is as defined above, in the presence or absence of water, and, if desired after isolation of the intermediate, with HY, [HL1]Y or [HL2]Y.
