bismethylation
« on: January 04, 2007, 05:09:47 PM »
Very odd ..i posted this and it didn't show ...oh well I'll try again..

I recently was studying a reaction when the term  "bismethylation" came on and wanting to know what they ment, the authors, I looked it up in goolge and no direct answer ...something about the adjacent carbon to the carbonyl ..? maybe dual methylation is occuring ...I have no clue aside that the article is about methylation ...any information?...java

Hello my "virtual friend" Java:

I saw a abstract on Australian Journal of Chemistry,  where the bismethylation reaction is used to prepare imide, which can be converted into the cis-diester...

Check this link: http://www.publish.csiro.au/nid/51/paper/CH9901941.htm (I don't have access to this journal)

Espero que hayas pasado unas felices fiestas de navidad y año nuevo en union de los tuyos!!!

Regards

Chiralic

Multiplying prefixes are used in much the same way to denote other identical structural features of a chemical compound, such as principal characteristic groups, sites of unsaturation, and number of ionic centers. However, the multiplying prefixes "bis-", "tris-", etc., are used instead of "di-", "tri-", etc., when the use of the latter would result in a potential ambiguity; for example, tris(decyl) is used to describe three decyl substituents because tridecyl is the name for a thirteen carbon acyclic substituent

So in the defination of bismethylation , it simply means two methylations....java
