Abstract
- In this work we report on the synthesis of new [PtCl(η 2 -CH 2 CH 2 )( N ˆ N )] + and [PtCl(η 1 -CH 2 –CH 2 OCH 3 )( N ˆ N )] complexes, with different N ˆ N dinitrogen ligands, i.e. ethylenediamine (en), R , R - and S , S -diaminocyclohexane ( R , R - and S , S -chxn), R , R - and S , S - N , N , N′ , N′ -tetramethyl-1,2-diaminocyclohexane ( R , R - and S , S -Me 4 chxn). In particular, the factors determining complex stability are highlighted, and discussed in relation to 1 H, 13 C and 195 Pt NMR chemical shifts exhibited by different complexes bearing hindered or unhindered diamine or diimine ligands.
