✦ Synopsis

We are reporting that the stereospecificity of cis-2-pentene's metathesis is much greater when the initiator is (C6H5)2C=W(CO)51 than when it is any other previously examined, that this high stereospecificity is similar to that shown by cyclic olefins, 3 and accordingly that no special mechanism is needed to account for why the stereospecificity of cyclic olefin metathesis is high. 2g,4 We indicate how the stereospecificity in the previously used initiating mixtures is diminished by Lewis acids.
