leads to [2-(4′-PyCH2NH–CH2)C6H4]SnPh3·BH3 (6), the first aryltin(IV) compound with a ligand containing a secondary amine functional group coordinated to the metal centre. The reaction of 4 with [PdCl2(NCMe)2] and [Cu(hfac)2·(H2O)] (hfac = hexafluoroacetylacetonate) in a 2 : 1 molar ratio gave the corresponding heterometallic complexes [2-(4′-PyCH2NCH2)C6H4SnPh3}2PdCl2] (7) and [2-(4′-PyCH2NCH2)C6H4SnPh3}2Cu(hfac)2]
[2-(CH 2 O)2 CH} C 6 H 4 ] SnPh 3(1)的水解导致[2-(O CH)C 6 H 4 ] SnPh 3(2)的分离屈服。用NaBH 4还原2可以得到几乎定量的[2-(HOCH 2)C 6 H 4 ] SnPh 3(3),当在没有任何溶剂的情况下用适当的胺处理2时,[2-(4' -PyCH 2 N CH)C 6 H4 ] SnPh 3( 4)和[2- 3',5'-(MeOOC) 2 –C 6 H 3 NCH} C 6 H 4 ] SnPh 3( 5)被高产率地分离出来。添加的NaBH 4到的THF溶液4根引线为[2-(4'- PyCH 2 -CH NH 2)C 6 H ^ 4 ] SnPh 3 ·BH 3( 6),所述第一aryltin( IV与配体)化合物含与金属中心配位的仲胺官能团 反应4用[PdCl 2(NCMe)2 ]和[Cu(hfac)2 ·(H 2
