METAL-THIOPHEN DERIVATIVES. ORGANOMETALLIC COMPOUNDS OF PALLADIUM AND PLATINUM

Thienylmercury(II)chloride reacts with , 4> and to afford new compounds containing a metal-2-thienyl linkage.The compound probably has trans stereochemistry. 2-Bromothiophen undergoes oxidative addition with and (Pt(PPh3)4>, probably via a radical mechanism.With , a carbonyl inserted product is obtained.The bromo-metal(II) complexes have trans stereochemistry.The course of the reaction between 3-methyl-2-bromothiophen and Pd(PPh3)4 is more complex.Thus, there is evidence of some cis bromopalladium(II) compounds amongst the products, also there is good evidence to support the view that some isomerisation of 3-methyl-2-thienyl to 4-methyl-2-thienyl occurs during the reaction, thus giving greater molar quantities of than can be accounted for from any initial 4-methyl-2-bromothiophen impurity.The metallation of the thiophen ring, probably in the 4-position, with palladium(II) is described for 3-thienylidene-4-methylaniline.
