Methylene
With the methyl group (methylene comes, methylene group), it is kind of the basis of 2 values in the organic chemistry.
I deal with the structure that two hydrogen was removed from methane.
The structure is expressed in -CH2- or form of =CH2.
Two atoms which the former connects the latter in the case of one.
It is the basis in the case of the latter in particular(methylidene group) can be called it.
Methylene chloride(CH2Cl2) It is the compound that a combination hand of 2 values of the methyl group was connected to two chlorine.
Methylene calls reaction to introduce methyl group into reaction.
I can get the alkene which carbonyl oxygen was replaced by with methyl group when I trigger a chemical reagent for a ketone and aldehyde.
It is carbene class CH: for alkene A cyclopropane derivative is provided as the product which became methylene when I trigger.
I can perform similar conversion by the Simmons Smith reaction with diiodomethane and zinc.
Organic zinc middle body called "IZnCH2I" becomes the active kind then.
Iodinated trimethyl sulfonium ((CH3)3SI) Is similar, and trigger a base; and sulfur ((CH3)2SCH2) I generate it, and methylene epoxide built a bridge is provided C=O double bond when I trigger a carbonyl compound to there.
This reaction is called Cory Tchaikovsky reaction.
I can change imine into aziridine.
