We have developed efficient catalytic methods for the stereoselective and diversity synthesis of various (E)-, (Z)-, and disubstituted 3-alkylideneoxindoles and 3-alkylidene-benzofuran-2-ones via palladium-catalyzed Heck/Suzuki-Miyaura, Heck/Heck, and Hec
An exploration of Suzuki aryl cross coupling chemistry involving [2.2]paracyclophane derivatives

Suzuki aryl cross coupling reactions using derivatives of [2.2]paracyclophane were examined. A variety of aryl boronic acids and pinacolate esters were successfully cross coupled with 4-bromo[2.2] paracyclophane under standard Suzuki conditions. Whilst an
STERICALLY HINDERED CYCLOPHANES. PART I. SYNTHESIS OF PHENYL DERIVATIVES OF - AND 2,11-DITHIAPARACYCLOPHANES

Some phenyl derivatives of 2,11-dithiaparacyclophane, substituted in the aromatic rings, have been obtained by the high dilution technique.Their photolysis yielded respective derivatives of paracyclophane.In the latter, rotation of phenyl substituents has been found to be hindered.
STERIC HINDERED CYCLOPHANES. PART II. THE SYNTHESIS OF 4-ARYLPARACYCLOPHANES IN THE CROSS-COUPLING OF GRIGNARD REAGENTS
Kus, Piotr,Zemanek, Aleksander
, p. 281 - 284 (2007/10/02)
The cross-coupling of Grignard reagents type Aryl-MgBr with 4-Br-paracyclophane catalyzed by complex of NiCl2 with PPh3 or Ph2PCH2CH2PPh2 was carried out. 4-Aryl-paracyclophanes were prepared in total yields of 10-65percent (Aryl=phenyl, o-tolyl, mesityl, α-naphthyl).The complex of NiCl2 with PPh3 was the most effective catalyst.
