- 中文摘要:
Cyclization occurred via the coupling reactions of some mercuric chloride derivatives of sydnone with LiPdCl/ sub 3/-Cu/Cl/sub 2/.
A unique six-membered ring, 3,3'-ethylene-4,4'- bissydnone, was obtained by the cyclization reaction of 1,2- di〔3-(4-chloromercuric)sydnonyl〕ethane. However, the seven-membered 3,3'-trimethylene-4,4'-bissydnone and 1,3-di〔3-(4-chloro)sydnonyl〕propane were obtained from the corresponding mercuric chloride of sydnone. Only substitution reaction took place when 4,4'-di〔3-(4- chloromercuric)sydnonyl〕biphenyl, 4,4'-di〔3-(4- chloromercuric)sydnonyl〕benzene, di{p-〔3-(4- chloromercuric)sydnonyl〕phenyl}methane and, di{p-〔3-(4-chloromercuric)sydnonyl〕phenyl}ether were treated using the same process. - 英文摘要: --
