Amidosulfites are chemical compounds containing the group =NS(O)O-. Substituents can attach two bonds to the nitrogen and one to the oxygen. These have the form RR'NS(O)OR" compounds can be a zwitterion with a positive charge on the nitrogen, and a negative charge on the oxygen, which then has no group attached. These can be called inner salts. This allows three groups to bond to the nitrogen: RR'R"N+S(O)O−.
The simplest amidosulfite is amidosulfurous acid H2NS(O)OH. It has ammonium salt H2NS(O)O−NH4+. These are purportedly produced when sulfur dioxide mixes with ammonia in ratios 1:1 or 1:2.
Known compounds include ''N''-(2-dimethylammonio-ethyl)amidosulfite, ''N''-(2-diethylammonio-ethyl)amidosulfite, ''N''-[2-(1-Piperidinium-1-yl)-ethyl]amidosulfite, ''N''-[2-(4-Morpholinium-4-yl)-ethyl]amidosulfite, sodium ''N''-ethylamidosulfite (C2H5NHS(O)ONa), Ethyl ''N''-ethylamidosulfite (C2H5NHS(O)OC2H5), diethyl-phosphanyl ''N''-methylamidosulfite, diphenyl-phosphanyl ''N''-methylamidosulfite, ''N'',''N''-dimethylamidosulfurous acid, ''N'',''N''-diethylamidosulfurous acid, ''N'',''N''-bis(2-hydroxyethyl)diethylamidosulfurous acid, sodium ''N'',''N''-dimethylamidosulfite, sodium ''N'',''N''-diethylamidosulfite, lithium ''N'',''N''-diethylamidosulfite, lithium ''N''-hexafluoroisopropylideneamidosulfite (with double bond to nitrogen), sodium 1-piperidinesulfinate Na(CH2)5NHS(O)O.
Organometallic substituents can produce for example trimethylsilyl ''N'',''N''-diethylamidosulfite, trimethyltin ''N'',''N''-dimethylamidosulfite, or dimethylthallium ''N'',''N''-dimethylamidosulfite.
