Site-specific preparation of 3-fluoro-1-substituted-naphthalenes via a novel base-catalyzed cyclization reaction from (E)-monofluoroenynes

A novel cyclization reaction for the preparation of 3-fluoro-1-substituted- naphthalenes is reported. (E)-Monofluoroenynes, which are prepared by Sonogashira coupling reaction from (Z)-1-bromo-1-fluoroalkenes, undergo cyclization to afford 3-fluoro-1-subs

The coupling of butylvinyltellurides with organometallic reagents catalysed by nickel complexes

Vinylic tellurides couple efficiently with sp, sp2 and sp3 hybridised organometallic compounds (Li, MgX and Zn species) in the presence of dichloro-bis(triphenylphosphine)nickel(II) as catalyst.

CuI-catalyzed Suzuki-Miyaura and Sonogashira cross-coupling reactions using DABCO as ligand

In the presence of TBAB, CuI-catalyzed Suzuki-Miyaura cross-coupling of vinyl halides and aryl halides with arylboronic acids was conducted smoothly to afford the corresponding diarylethenes and polyaryls in moderate to good yields using DABCO (1,4-diazabicyclo[2.2.2]octane) as the ligand. We also found that the inexpensive CuI/DABCO catalytic system was effective for Sonogashira cross-couplings of aryl halides and vinyl halides. A variety of aryl halides and vinyl halides including activated aryl chlorides underwent the coupling with terminal alkynes in moderate to excellent yields.

Coupling of butyl vinyl tellurides with metal acetylides catalyzed by nickel complexes

Z-Vinylic tellurides react with metal acetylides under nickel complexes catalysis to give Z-enynes and Z-enediynes in good yields.

Stereoselective synthesis of enynes by nickel-catalyzed cross-coupling of divinylic chalcogenides with alkynes

(Z,Z)- and (E,E)-divinylic selenides and telurides undergo direct coupling with terminal alkynes in the presence of a nickel/CuI catalyst at room temperature to give (Z)- and (E)-enyne systems in good yields and with complete retention of configuration.

Stereoselective synthesis of (Z)-enynes via Pd(II)/CuI(I)-catalyzed cross-coupling reaction of bis-Vinylic tellurides with 1-alkynes

(Z)-bis-Vinylic tellurides undergo direct coupling reaction with terminal alkynes in the presence of palladium (II) at room temperature to give (Z)-enyne systems in good yields.

Coupling of Z-vinylic tellurides with alkynes catalysed by PdCl2/CuI: Synthesis of Z-enynes and Z-enediynes

Vinylic tellurides of the Z-configuration couple with alkynes under PdCl2/CuI catalysis to give enynes and enediynes in good yields and with retention of the double bond configuration.

Substituted 4-(alk-2-ynylsulfinyl)morpholines: preparation and conversion into substituted allenes by hydrolytic desulfinylation

4-(Alka-1,2-dienylsulfinyl)morpholines 1 were converted into the title compounds 2 by γ-deprotonation with methyllithium via a complex-induced proximity effect (CIPE) process, followed by reaction with electrophiles.Compounds 2 were hydrolysed or deuterol
