WebOur initial reaction conditions mirrored those developed in the reactions of trimethylsilyl halides (catalytic (COD)Pd(CH2TMS)2 (2) and tBuPPh2 with stoichiometric LiI and Et3N at 60 °C). When ethanol was added at the beginning of the reaction, modest yield of the desired ethoxyvinylsilane 3a resulted (26%, Table 1, entry 1). WebA sterically bulky ligand, tBuPPh2, affords para-acylated products 3, whereas a sterically less bulky ligand, Me2PPh, provides ortho-acylated products 4. Further, direct substitution product 5 at the benzylic position is not obtained essentially, although such a reaction at the benzylic position is favorable in ordinary nucleophilic substitutions. WebBulky ligand tBuPPh2 generates para-substituted products, while small ligand Me2PPh provides ortho-substituted products. Herein, the density functional theory calculations … lapisera do deku
