摘要:
Manganese bromide solution for use in the formation of organomanganese compounds, applicable to the synthesis of organic products, particularly ketones.
摘要:
Process of preparation of alcohols by the reaction of an organic halide with a carbonyl compound in an organic solvent, in the presence of metallic manganese, followed by hydrolysis of the reaction product; the reaction is initiated and activated by an ester present in the reaction medium.
摘要:
Process of preparation of secondary or tertiary alcohols by the action of an organic halide on metallic manganese, in the presence of a carbonyl compound in a solvent followed by hydrolysis; a compound of a metal of Groups II to VIII of the Periodic Classification of the Elements, less electropositive than manganese, is present in the reaction medium.
摘要:
Process of preparation of ketones by the reaction of an organo-metallic compound with a compound carrying a carbonyl, within a solvent, in the presence of a manganous salt as catalyst. The manganous salt is in the form of a double salt of Mn and an alkali metal cation.
摘要:
A method of preparing manganous enolates by the treatment of alkali metal or alkaline earth metal enolates with manganous compounds in a solvent for the Mn enolate to be prepared.
摘要:
The invention relates to a process for preparing Grignard compounds of the formula I. The invention additionally relates to compounds of the formula I and to polymer-bound compounds of the formula Ia. The invention further relates to the use of the process for preparing substance libraries and to the use of the compounds of the formulae I and Ia in chemical synthesis.
摘要:
A process for the stereoselective preparation of Grignard compounds of the formula I and polymer-bonded compounds of the formula Ia is described. The process can be used for producing substance reference libraries and the compounds of the formulae I and Ia can be used in stereoselective chemical synthesis.
