Reactivity of Tin(II) Guanidinate with 1,2-and 1,3-Diones: Oxidative Cycloaddition or Ligand Substitution ?

Popis výsledku v původním jazyce

A series of tin(IV) guanidinates were prepared by a (4+1) oxidative cycloaddition of four 1,2-diones (3,5-di-tert-butyl-o-benzoquitione, 8,4,5,6-tetrachloro-1,2-benzoquinone, 9;10-phenanthrenedione, 1,2-diphenylethanedione) or by an oxidative addition ofa C-Br bond (from 2-bromo-1,3-diphenylpropane-1,3-dione followed by rearrangement) and a Cl-Cl bond (Cl-2 generated from (dichloro-lambda(3)-iodanyl)benzene), with {pTol-NC[N(SiMe3)(2)]N-pTol}(2)Sn (1). The reactivity of five pentane-1,3-diones and dimethyl malonate with compound 1 was assessed on the basis of the effect of 1,3-diones on the reaction mechanism in comparison with 1,2-diones. In contrast with oxidation reactions observed for compounds containing conjugated C=O bonds, the reactions of thetin(II) guanidinate with 1,3-diones revealed a high ability for ligand substitution. All the tin compounds prepared were characterized, and ligand substitution reactions were monitored using H-1, C-13, and Sn-119 NMR spectroscopy. The mo
