Abstract: A 3-(hydrocarbylthio)propionaldehyde is reacted with a compound ……R min @X… to make a compound of the formula ……RSCH2CH=CHO@R min ;… this latter compound is reacted with CO and R sec YH where Y is O or S to make … … this compound is hydrolyzed to produce methionine hydroxy analog or a derivative thereof. The process avoids the use of HCN. 1-Propionyloxy-3-methylthiopropene and the methyl ester of 2-acetoxy-4-(methylthio)thiobutanoic acid are disclosed as new compounds.

Abstract: A process for dimerizing acrylonitrile to produce adiponitrile and/or 1,4-dicyanobutenes comprises contacting acrylonitrile with a catalyst at a temperature of 20 to 250 DEG C in the presence of hydrogen, said catalyst comprising a polymer support having a ruthenium complex bonded thereto, said polymer support comprising an organic polymer backbone having trivalent pendant atoms selected from P, As, Sb, Bi and N covalently bonded thereto and randomly distributed in said polymer, said ruthenium complex being capable of catalyzing the dimerization of acrylonitrile to adiponitrile and/or 1,4-dicyanobutenes and comprising Ru and at least two homogeneous ligands having at least four ligating bonds bonding to said Ru, the Ru in each ruthenium complex datively bonding to a pendant atom in said polymer support, the Ru/pendant atom ratio in said catalyst being at least 0.001, said complex having on the average no more than one homogeneous phosphine ligand per atom of ruthenium. … Preferred ruthenium complexes are those which are substantially free of homogeneous phosphine ligands. The organic polymer support can be a terpolymer of 2-20% divinyl benzene, 0.4 to 6% para-diphenylphosphenostyrene and the balance styrene.
