I added some references to the biological activity section expanded it a tiny bit. I'm sort of a noob to wikipedia and two of my references look a little funny but I can't figrue out why. If someone could fix them, that would be great. They are the last two references in the biological activity page. Also, I agree a quaternary amine should be added to the top graphic. I'll try to remake the graphic when I have time if no one else can get around to it.[[User:RabidRabbit23|RabidRabbit23]] ([[User talk:RabidRabbit23|talk]]) 09:38, 29 January 2011 (UTC) |

== Use Iodine pentafluoride to make nitrile from primary amine -- sourced? == |

== Table of Kb values == |
|||
Primary amines react with [[iodine pentafluoride]] forming nitriles.[3] |
|||
Somebody, please set the table of Kb values right. I added some content, and then, extra values to support it (and messed up the format). |

Is there a special name for compounds where the -NH2 is bonded to a non-carbon atom, such as a metal or metalloid? How much study has there been into such compounds? Looking around online, it seems like silicon amines exist, and are used in the manufacturing of [[silicon nitride]] among other things, but there should be more info about them on Wiki.

This page's content is so problematic that it likely should be pulled, and recast, only including information that can be entered with certainty, from reliable, verifiable sources. Web citing web IS NOT enough for a reliable encyclopedia entry. (This said, because I have found enough discrepancies, that I cannot recommend.)

== Sentence problem == |
|||
This sentence is giving me trouble, mostly b/c I'm not an organic chemist, but if it's confusing to me it's likely to be confusing to others. Anyway I hope someone could clarify and then update it in the article: |
|||
"However, if any of the carbons bonded to the nitrogen that is part of a carbonyl group, then the compound is considered an amide rather than an amine." |
|||
Does this mean -- if any of the carbons in the 'R' group are, in turn, part of a carbonyl group, then the whole deal is an 'amide' instead of an 'amine' |
|||
:basically 'that is' is ambiguously referring to one of 'the nitrogen' or 'the carbons' |
|||
Thx. |
|||
:: [[User:hmackiernan|Harold MacKiernan]] 5 Jan 2006 23:11 PST |
|||
I'm pretty sure that any carbonyl group adjacent to an N, NH or NH<sub>2</sub> makes it an amide. Perhaps: |
|||
"However, '''if any of the carbons bonded to the nitrogen are also part of a carbonyl group''', then the compound is considered an amide rather than an amine." |

== Drawing == |
|||
Nice drawing for the nitrile and amide reductions by LAH, but you might revise the nitriles so that R-C-N are linear in the starting material.--[[User:Smokefoot|Smokefoot]] 04:52, 20 February 2006 (UTC) |
|||
also the amide forming reaction from acid chloride and an alkyl amine is incorrect as one CH2 was lost.--[[User:Smokefoot|Smokefoot]] 00:58, 22 February 2006 (UTC) |
|||
==Properties as bases== |
|||
the [[Amine#Properties as bases|article]] says that:<br> |
|||
The nitrogen atom features a [[lone electron pair]] that can bind H<sup>+</sup> to form an [[ammonium ion]] R<sub>3</sub>NH<sup>+</sup>. |
|||
The wiki page about [[ammonium ion]] says that its formula is NH<sub>4</sub><sup>+</sup>. <br> |
|||
Could somebody correct this ?<br> |
|||
What is the name of R<sub>3</sub>NH<sup>+</sup> ? |
|||
--[[User:Colonna|Colonna]] 13:36, 25 April 2007 (UTC) |
|||
:"Ammonium" can refer either to NH<sub>4</sub><sup>+</sup> itself or more generally to compounds with four groups attached to a positively charged nitrogen - R<sub>4</sub>N<sup>+</sup>. NH<sub>4</sub><sup>+</sup> is just the case where the four R groups are hydrogens and R<sub>3</sub>NH<sup>+</sup> is the case where only one is. --[[User:Edgar181|Ed]] ([[User talk:Edgar181|Edgar181]]) 14:03, 25 April 2007 (UTC) |

== Classes of amine == |
|||
Should cyclic nitrogen containing organics such as [[pyrroles]] be included as a class of amine? At least one of the molecular structures shown in [[pyrroles]] meets the definition given in the lead for an amine. If pyrroles are not amines, then that should be mentioned as it is likely many readers would think they are. [[User:Qemist|Qemist]] ([[User talk:Qemist|talk]]) 00:12, 2 May 2010 (UTC) |
