| Abstract: | A series of (Z,Z)-tetraaryl-1,3-butadienes has been synthesized stereospecifically and regioselectively by acidolysis of five-membered Ti, Zr metallocycles formed from asym. substituted ethynes. E.g., stirring 4-MeC6H4CYCPh with zirconocene dichloride and sodium in THF gave 63% butadienes I and II (I/II = 95/5). |
