摘要:
The oxidative addition of cyclopropylmethyl or cyclobutylmethyl bromide to [PtMe2(bipy)], 1. bipy=2,2'-bipyridine, gave the products of trans-oxidative addition [PtBrMe2(CH2-c-C3H5)(bipy)], 2. or [PtBrMe2(CH2-c-C4H7)(bipy)], 3. These compounds are thermally stable but the complex [Pt(O2CCF3)Me-2(CH2-c-C3H5)(biPY)] rearranges on heating to give the ring-opened complex [Pt(O2CCF3)Me-2(CH2CH2CH=CH2)(bipy)]. Factors affecting the reactivity towards ring-opening are discussed. (c) 2010 Elsevier B.V. All rights reserved.
