  Platinum-Catalyzed Reaction of Alkynes with ArI (Ar = aryl and thienyl) and Ar‘SM (M = Na, K, and Sn(Bu-n)₃):  Three- vs Two-Component Cross-Coupling Reaction

  摘要：

  The Pt-catalyzed reactions of terminal alkynes HCCR (2) with ArI (6) (Ar = aryl and thienyl) and Ar'SM (M = Li, Na, K, and Sn(n-Bu-3)) (7) have been examined. Among them, the combined use of 2- and 3-iodothiophene with PhSK resulted in the formation of (Z)-Ar(H)C=C(SAr')(R) (5) in moderate to good yields. When aryl iodide was employed as a coupling partner, thioether ArSAr' (4), a direct cross-coupling product between 6 and 7, was competitively produced together with 5. The ratios of formation of 514 were significantly dependent on the substituent in Ar of 6 and Ar' of 7 as well as species of 2. The mechanistic study indicated that 4 was produced by the alkyne-participated reaction of 6 with Pt(Ar)(SAr')(PPh3)(2) (1).

  (2). Each of the complexes is isolated and characterized by X-ray crystallography and/or NMR spectroscopy. The 31P1H}-NMR study of the reaction of AgBF4 with PtI2(PPh3)2 in acetone-d6 revealed the formation of trans-[PtI(PPh3)2(acetone)]BF4 (3) although isolation of the cationic complex was not feasible due to its facile conversion to 2.
