7Is this 1H-Borepin – Mesentery May 14 '17 at 16:41

@blue I used CPK coloring code for atoms. See https://en.wikipedia.org/wiki/CPK_coloring – Pritt says Reinstate Monica May 15 '17 at 00:45

4@PrittBalagopal You should mention that in your question to avoid confusion. I wasn't sure what colouring scheme you were using. – May 15 '17 at 01:04

According to the current version of Nomenclature of Organic Chemistry – IUPAC Recommendations and Preferred Names 2013 (Blue Book), heteromonocyclic compounds with up to and including ten ring members are named by the extended Hantzsch–Widman system. According to P-68.1.1.3.2, this also applies to heterocyclic parent hydrides containing Group 13 (boron group) atoms.
The Hantzsch-Widman system stem for an unsatured 7-membered ring is “epine”. Therefore, the preferred name for the compound that is given in the question is 1H-borepine.
The name 1H-1-boracyclohepta-2,4,6-triene is not recommended.

2Unsaturated or fully conjugated 7-member ring? Do we use epine for the cycloalkene formulated C7H12? – Oscar Lanzi May 14 '17 at 17:48

Then presumably the words "fully conjugated" should be used instead of "unsaturated". – Oscar Lanzi May 17 '17 at 23:14

If the black coloured are carbon atoms and the white coloured are hydrogen atoms, and the pink one is Boron. Then it should be 1H-Borepine.
[See here for why it is aromatic.

4There is a standard color code for ball and stick models. True, carbon = black, hydrogen = white, boron = that pretty pink color. Some others : oxygen = red, nitrogen = blue, chlorine = yellowish green like the gas. – Oscar Lanzi May 14 '17 at 17:41

1@Mesentery Thanks for your answer. There is in fact a color code for atoms. See https://en.wikipedia.org/wiki/CPK_coloring – Pritt says Reinstate Monica May 15 '17 at 00:42
