The potassium bis-dithiocarbamate (bis-dtc) salts of 1,3- bis(benzylaminomethyl)benzene (1,3-Bn-ambdtc), 1,3-bis(iso-butylaminomethyl) benzene (1,3-iBu-ambdtc), 1,4-bis(benzylaminomethyl)benzene (1,4-Bn-ambdtc), and 1,4-bis(iso-butylaminomethyl)benzene (1,4- iBu-ambdtc) were reacted with three different diorganotin dichlorides (R2SnCl2 with R = Me, nBu, and Ph) in 1:1 stoichiometric ratios to give the corresponding diorganotin bis- dithiocarbamates. Additionally, the dimethyltin bis-dithiocarbamate of 1,1?-bis(benzylaminomethyl)ferrocene (1,1?-Bn-amfdtc) was prepared. The resulting complexes have been characterized as far as possible by elemental analysis, FAB+ mass spectrometry, IR and NMR (1H, 13C, and 119Sn) spectroscopy, and single-crystal X-ray diffraction, showing that the tin complexes are dinuclear 24- and 26-membered macrocyclic species of composition [{R2Sn(bis-dtc)}2]. As shown by 119Sn NMR spectroscopy, the tin centers are hexa-coordinated in all cases; however, two different coordination environments are possible, as detected by single-crystal X-ray diffraction. In the dimethyltin derivatives of 1,3-Bn-ambdtc, 1,3-iBu-ambdtc, 1,4-Bn-ambdtc, and 1,1?-Bn-amfdtc and the di-n-butyltin derivative of 1,3- iBu-ambdtc, the metal atoms are embedded in skewed-trapezoidal- bipyramidal coordination polyhedra with asymmetrically coordinating trans-oriented dtc groups. In contrast, in the diphenyltin derivative 1,3- iBu-ambdtc, the metal centers have distorted octahedral coordination with symmetrically coordinating cis-oriented dtc functions. Thus, for the complexes derived from 1,3-Bn/iBu-ambdtc, two different macrocyclic structures were observed. In the dimethyl- and di-n-butyltin derivatives, the bridging bis-dtc ligands adopt U-shaped conformations, while in the case of the diphenyltin derivative, the conformation is L-shaped. Furthermore, two different macrocyclic ring conformations can occurr, which differ in the spatial orientation of the substituents attached to the nitrogen atoms (Bn or iBu). The dimethyltin derivatives of 1,4-Bn-ambdtc and 1,1?-Bn-amfdtc have cavities, in which aromatic rings are accomodated in the solid state.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. We’ll also look at important developments of the role of 1271-48-3, and how the biochemistry of the body works.Electric Literature of 1271-48-3
