A slow addition alsoreduces the temperature in the reaction and suppresses the formation of biphenyl because the formation of the Grignard reagent is favored at lower temperatures. If he added the solution too rapidly, the reaction mixture would foam very heavily and turn dark brown. When was Gri...

What is Grignard synthesis? The Grignard reaction (French: [ɡʁiɲaʁ]) is an organometallic chemical reaction in which alkyl, allyl, vinyl, or aryl-magnesium halides (Grignard reagent) is added to a carbonyl group in an aldehyde or ketone. This reaction is important for the formation...

i think the Diketone might have the same mechanism as any other ketone, but i have never seen the circumstance which the five phosphor can reactive as a reductive reagent.is it possible in mechanism? Logged Ulfsaar Regular Member Posts: 26 Mole Snacks: +2/-0 Re: what's the mechanism?
The reason I was skeptical was I can find many examples in which electrons are added to the carbonyl carbon, but I was not aware of a single example of an addition to the oxygen. For example, if it adds to the oxygen, then addition of a methyl Grignard to a bromoketone ought to giv...
The Grignard ReactionA Grignard reaction is a reaction in organic chemistry that can be used for the formation of an alcohol. This organometallic reaction requires the use of a Grignard reagent, which is an alkyl, allyl, vinyl, or aryl-magnesium halide (usually written in the form of RMgX...
