Abstract:
The present invention refers to a process for a transition metal, particularly nickel-catalyzed cyanation reaction of aryl/vinyl halide using organic nitrile compounds. This new reaction provides a strategically distinct approach to the safe preparation of aryl/vinyl cyanides, which are essential compounds in agrochemistry and medicinal chemistry.
Abstract:
The present invention refers to processes for catalytic reversible alkene-nitrile interconversion through controllable HCN-free transfer hydrocyanation.
Abstract:
The present invention relates to a process for the asymmetric oxidation of nucleophilic organic compounds, particularly metal-free, with peroxide compounds in the presence of a chiral Brønsted acid catalyst. In one detail, the present invention relates to a process for enantioselective sulfoxidation of thiocompounds with peroxide compounds in the presence of a chiral imidodiphosphate catalyst. In another detail, the present invention relates to a process for enantioselective sulfoxidation of thiocompounds with peroxide compounds in the presence of a chiral phosphoric acid catalyst.
Abstract:
The invention relates to surfactants of the formula (I), in which R1 stands for —H or —CH3; R2, R3, R4, R5, R6 independently stand for —H, —CH3, —CH2CH3, —CH2CH2CH3, —CH(CH3)2, —CH2CH2CH2CH3, —CH2CH(CH3)2, —CH(CH3)CH2CH3, —C(CH3)3, —OH, —OCH3, —OCH2CH3, —OCH2CH2CH3, —OCH(CH3)2, a linear or branched alkyl group containing 8 to 20 C atoms, or —SO3−X+; X+ stands for a monovalent cation or the nth part of an n-valent cation; exactly one radical R2, R3, R4, R5, R6 stands for —SO3−X+; and exactly one radical R2, R3, R4, R5, R6 stands for a linear or branched alkyl radical containing 8 to 20 C atoms.
Abstract:
The present invention refers to a process for the trans-selective hydroboration of internal alkynes and the so-obtained products. The inventive process makes use of a borane of the formula X1X2BH selected from the group of dialkyl boranes or di(alkoxy)boranes which are reacted with the internal alkynes in the presence of a cyclyopentadienyl-coordinated ruthenium catalyst.
Abstract:
The present invention discloses a process for the conversion of phenolics into aromatic hydrocarbons. In more detail, the present invention refers to a process for the selective hydrodeoxygenation of phenolic feeds into aromatic hydrocarbons, such as benzene, toluene, alkylbenzenes and others. The selective catalytic hydrodeoxygenation is performed in absence of external supply of molecular hydrogen.
