The Pd(II) complexes [Pd(acac)(L)_n]BF4 were synthesized by the reaction of [Pd(acac)(MeCN)₂]BF₄ with L (n = 2: L = PCyPh₂, PCy₂Ph, P(NMe₂)₃, P(NEt₂)₃, tri-2-furylphosphine, tri-2-thienylphosphine; n = 1: L = 2 dicyclohexylphosphino-2′,6′-dimethoxybiphenyl, 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl). The structural features of the complexes were analyzed by NMR and FTIR spectroscopies. Complexes [Pd(acac)(PCyPh₂)₂]BF₄ and [Pd(acac)(PCy₂Ph)₂]BF₄ were characterized by X-ray diffractometry. The cationic palladium catalyst precursors were found to be active catalysts for telomerization of 1,3- butadiene with methanol under base-free conditions. Complexes [(acac)Pd(PCy₂Ph)₂]BF₄ and [(acac)Pd(TOMPP)₂]BF₄ in terms of yield, selectivity, and stability are effective for the catalytic telomerization (TOMPP = tris(2-methoxyphenyl)phosphine). Using 0.001–0.0025 mol% palladium loading methoxy-2,7-octadienes were obtained with chemoselectivities of 76–94% and TON up to 60000 mol 1,3-butadiene per mol Pd.

通过[Pd（acac）（MeCN）₂ ] BF ₄与L（n  = 2：L = PCyPh ₂，PCy ₂ Ph的反应）合成了Pd（II）配合物[Pd（acac）（L）_n ] BF4 ，P（NMe ₂）₃，P（NEt ₂）₃，三-2-呋喃基膦，三-2-噻吩基膦；n  = 1：L = 2二环己基膦基-2'，6'-二甲氧基联苯，2-二环己基膦基-2' ，4'，6'-三异丙基联苯）。通过NMR和FTIR光谱分析了配合物的结构特征。复合物[Pd（acac）（PCyPh ₂）₂ ] BF ₄和[Pd（acac）（PCy ₂ Ph）₂ ] BF ₄通过X射线衍射法表征。发现阳离子钯催化剂前体是用于在无碱条件下用甲醇将1，3-丁二烯端粒化的活性催化剂。就产率，选择性和稳定性而言，配合物[（acac）Pd（PCy ₂ Ph）₂ ] BF ₄和[（acac）Pd（TOMPP）₂ ] BF ₄对于催化端粒化有效（TOMPP =  tris（2-甲氧基苯基）膦）。使用0.001-0.0025 mol％的钯负载量，可获得甲氧基-2,7-辛二烯，化学选择性为76-94％，TON的摩尔选择性最高为每mol Pd 60000 mol 1,3-丁二烯。
