Abstract:
The substituent exchange reaction of PhSnCl 3 with [Et 3 Sn(OCH 2 CH 2 NMe 2 )] gives rise unexpectedly to the unsymmetrical adduct [Ph 2 SnCl 2 · Ph 2 Sn(OCH 2 CH 2 NMe 2 ) 2 ] ( 2 ). It has been unambiguously proved for the first time that compounds of the RSnX 3 type are able to undergo the hydrocarbon substituent redistribution reaction. The analogous tin complexes [Et 2 SnCl 2 · Et 2 Sn(OMe) 2 ] ( 5 ) and [Bu 2 Sn(OAc) 2 · Bu 2 Sn(OMe) 2 ] ( 6 ), which have ligands other than β‐dimethylaminoethoxy and could be considered as “organotin analogs of Grignard reagents” have symmetrical dimeric structures, i.e., can be formulated as [Bu 2 Sn(OMe)(OAc)] 2 and [Et 2 Sn(OMe)Cl] 2 , respectively. Both types of structures, viz., unsymmetrical adduct ( 2 ) and symmetrical dimer ( 5 , 6 ), have been characterized by X‐ray diffraction analysis. (© Wiley‐VCH Verlag GmbH & Co.
