It's important
In coordination chemistry phenylenediamine is an important ligand precursor, as it is quinoid giving rise to electronically delocalized complexes. It condenses with many carbonyls to give rise to Schiff bases that are of significance in coordination chemistry. It is a key building block in heterocyclic chem, for example the quinoxalines are prepared by condensation with dimethyloxalate. Benzimidazoles are prepared by it also. Benzimidazole is the axial base in vitamin b12.--Smokefoot 04:51, 19 June 2006 (UTC)
- Hey cool, now the talk page has way more information than the article itself. =P —Keenan Pepper 05:02, 19 June 2006 (UTC)
Name
Do people in the business call this o-phenylenediamine or should I move this to 1,2-diaminobenzene (and its two isomers similarly)? —Keenan Pepper 05:09, 19 June 2006 (UTC)
I havent fathomed or tried to understand the WE-chem official position on naming, so I leave that to the WE wonks and then put in redirects as needed. I am only a content guy.--Smokefoot 05:12, 19 June 2006 (UTC)
Boiling point
Both mp and bp are indicated very differently in different sources, but the bp is listed as 256 - 258 °C in a few.[1] [2] In at least one book, too - as it is in Russian I do not put the refernce here. 159.148.226.100 (talk) 15:03, 8 May 2011 (UTC)
