- REACTIONS OF ORGANOMETHALIC COMPOUNDS CATALYZED BY THE COMPLEXES OF TRANSITION METALS. I. COUPLING OF ORGANOTIN COMPOUNDS WITH ARYL HALIDES CATALYZED BY PALLADIUM COMPLEXES
-
The reactions of organotin compounds RSnMe3 C, C9H7 (indenyl), C13H9 (9-fluorenyl)> with aryl halides ArX , catalyzed by palladium complexes ArPdI(PPh3)2 in dichloroethane under vacuum conditions were investigated.In the reactions of RSnMe3 (where R = Ph, m-CH3C6H4, or PhCC) the RAr compounds are formed with good yields.In the stoichiometric reactions of RSnMe3 (where R = Ph or PhCC) with ArPdI(PPh3)2 (where Ar = Ph, p-NO2C6H4, or 2,4-(NO2)2C6H3> the dimers R2 are formed in addition to RAr, while in the case of the reactions of RSnMe3 (where R = C9H7 or C13H9) only R2 compounds are obtained.The possible mechanisms of the catalytic and stoichiometric reactions are discussed.
