Reaction of [Pt4(μ-OCOCH3)8] (1) with 1 equiv of acrylic acid led to the selective monosubstitution of one of the four in-plane acetates in 1, affording [Pt4(μ-OCOCH3) 7(μ-OCOCH=CH2)] (2a), whereas treatment with excess amounts of acrylic acid resulted in a full-substitution of four in-plane acetates, yielding [Pt4(μ-OCOCH3)4(μ- OCOCH=CH2)4] (3). Similarly, monosubstituted heptaacetate complexes [Pt4(μ-OCOCH3)7{μ-OCO(CH) nCH=CH2}] (2b-2d: n = 1-3) were prepared. Catalytic intermolecular coupling reactions of 2c and 2d assisted by Grubbs' catalysts gave the desired dimers [{Pt4-(μ-OCOCH3) 7}2{μ-OCO(CH2)nCH=CH(CH 2)n(μ-OCO)}] (6c: n = 2; 6d: n = 3). Copyright
