| titleOfInvention | Piperazino-stannonium compounds |
| abstract | The invention comprises piperazino-stannonium compounds of formula [RmSn(Pip)y]X4-m wherein m is 2 or 3; y is 1 or 2 and the R groups, which may be the same or different, represent aromatic, aliphatic or heterocyclic groups which may contain innocuous substituents. R may represent an alkyl or alkenyl groups having up to 22 carbon atoms in the chain, alkaryl or aralkyl groups having up to 22 carbon atoms in the alkyl chain, aryl groups containing one or two aromatic rings or heterocyclic group. X is defined as a halogen atom; a group ORa or SRa wherein Ra is an alkyl, alkenyl, aryl, aralkyl or alkaryl group which may contain an innocuous substituent; the residue of a carboxylic acid, an ester thereof, a mercapto acid, an ester thereof, an aryl sulphonic acid, a sulphonamide, a dithiocarbamate, an isodithiocarbamate or a xanthate. Typical X groups specified include residues of acids such as acetic, lactic, stearic, maleic, malic, fumaric, citric, phthalic or benzoic acids; butoxy, lauroxy and phenoxy groups and their sulphur analogues and the residues of a -mercaptolauric acid, mercaptoethanol iso-octyl mercaptoacetate and laurylmercaptan. The group "Pip" is defined as an amine of formula <FORM:0815819/IV (b)/1> wherein R1, R2, R3 and R4 may be the same or different and represent hydrogen or an aromatic, aliphatic, or heterocyclic group which may contain innocuous substituents and Z is hydrogen or an innocuous substituent. The compounds of the invention may be prepared by mixing compounds of formula R2SnX2 or R3SnX with the desired piperazine with agitation and heating if necessary. A list of suitable R2Sn- and R3Sn groups is given. Specified piperazino - stannonium compounds include mono - [N,N1 - bis(4 - nitrophenyl) piperazino]-tricresyl stannonium butoxide, bis-(N,N1-diphenylpiperazino) butyl thienyl stannonium dip - toluene - sulphonamide, bis - (N,N1 - di - p-tolyl piperazino) - diallylstannonium dibenzenesulphonate, bis - (N,N1 - di - p - tolylpiperazino - mono - hydroxymethylate) trioctylphenylstannonium citrate, mono - [N,N1 - bis (3 - oxyphenyl) - piperazino] diphenylstannonium maleate, bis - (N - acetylpiperazino) dihexylstannonium, S,S1 - bis - (mercaptoethyllaurate), bis - (piperazino - N,N1 - dicarboxyldimethyl ester) tributyl stannonium methoxide, mono - (N,N1 - dichloropiperazino) triallylstannonium diethyl isodithiocarbamate, bis-[N,N1 - dinitroso(dinitro)(diamino) - piperazino]-tripyridylstannonium chloride, bis (2,3,5,6-tetrabutylpiperazino) dinaphthylstannonium dibromide, bis - (41 - bromo - 3,21 - dinitro - 4-piperazinodiphenyl) tribenzylstannonium phenoxide and bis-(N,N1-bis-chloroacetyl piperazino)-dicarbethoxyethyl methylstannonium dimethacrylate. In an example tributyltin acetate is reacted with piperazine to yield mono-(piperazino) tributylstannonium acetate. Many other examples are given. |
