Oxidative Addition of HP(O)Ph₂ to Platinum(0) and Palladium(0) Complexes and Palladium-Catalyzed Regio- and Stereoselective Hydrophosphinylation of Alkynes

Oxidative addition of Ph2P(O)H to M(PEt3)3 (M = Pd, Pt) readily took place at room temperature in benzene to afford cis-MH[P(O)Ph2][PPh2(OH)](PEt3) complexes. The structure of the platinum complex was determined by X-ray crystallography. The palladium complex was found to undergo an insertion reaction with oct-1-yne to give 1- and 2-(diphenylphosphinyl)oct-1-enes. Pd(PPh3)4 catalyzed regio- and stereoselective synthesis of alkenyldiphenylphosphine oxides (hydrophosphinylation) from alkynes and Ph2P(O)H

Palladium-Catalyzed Borylstannylative Carbocyclization of Diynes and an Enyne Compound

Highly regio- and stereoselective borylstannylative carbocyclization of diynes 2a−f with the borylstannane 1 are efficiently catalyzed at room temperature by a series of palladium complexes such as Cl2Pd(PPh3)2, Cl2Pd[P(o-tolyl)3]2, Pd(PPh3)4, and Pd(dba)2, giving 1-(borylmethylidene)-2-(stannylmethylidene)cycloalkane derivatives 3a−f in high yields. A 1,6-enyne (2g) also reacts similarly to afford a high yield of the corresponding cyclized product 3g

Dehydrocoupling of Phenylsilane Catalyzed by (Dimethylamino)alkyl- or Branched-Alkyl-Substituted Zirconocene Complexes: An Alternative Approach to Longer Chains

New zirconocene complexes Cp*[Cp(CH2)nNMe2]ZrCl2 (n = 2, 3) and Cp*[Cp(CH2)nCH(CH3)2]ZrCl2 (n = 1, 2) catalyze, in conjunction with 2 equiv of n-BuLi, dehydrocoupling polymerization of phenylsilane to afford high-molecular-weight poly(phenylsilanes) (Mw > 104). 29Si NMR reveals that the microstructure of the resulting polymers is predominantly syndiotactic
