A Practical Synthesis of 2,6-Dicarboxyfluorenone

Herein, we report a new and efficient method for the large scale synthesis of 2,6-dicarboxyfluorenone 5 in 95% yield using 0.01 mol% of bis(triphenylphosphine)palladium(II) chloride, (PPh3)2 PdCl2, as a catalyst, starting

Regioselectivity switch achieved in the palladium catalyzed α-arylation of enones by employing the modified Kuwajima-Urabe conditions

A new regioselective approach to the synthesis of α-aryl enones is reported. This represents an important application of the Kuwajima-Urabe protocol toward the synthesis of this simple albeit complex functional array. Several α-aryl enones were synthesized by the palladium catalyzed arylation of triethylsilylenol ethers of enones with high regioselectivity and broad scope, utilizing sterically encumbered electron-rich phosphine ligands to drive the reaction.

Phenyl Cations as Reactive Intermediates in the Solvolysis of Dien-in-yl Triflates

The synthesis, separation, and solvolysis of the stereoisomeric 1,4-dimethyl-1,3-hexadien-5-yn-1-yl triflates 15a - c in various solvents are described.In contrast to the (Z)-isomers 15a - c, the (E)-isomers 15a - c react preferably via an intermediate phenyl cation 16 to give the phenyl ethers 17.Further mechanistic investigations which support the formation of the intermediate phenyl cations 16 are described.The formation of the benzylic derivatives 18 is discussed.
