Imazaki, Yusuke,Shirakawa, Eiji,Hayashi, Tamio
experimental part, p. 10212 - 10215 (2012/01/05)
A ruthenium complex coordinated with 3,4,7,8-tetramethyl-1,10- phenanthroline catalyzed the reaction of alkenyl triflates with zinc dithiolates to give alkenyl sulfides.

A new oxapalladacycle 3 can be conveniently prepared via direct ortho palladation of diphenylphosphinic acid with palladium acetate. Catalysts derived from 3 can efficiently catalyze Markovnikov-type additions of E-H bonds (P(O)-H, S-H and spC-H) to alkyn
Stereo-recognizing transformation of (E)-alkenyl halides into sulfides catalyzed by nickel(0) triethyl phosphite complex

(E)-Alkenyl halides were transformed into (E)-alkenyl sulfides by the nickel(0) triethyl phosphite complex-catalyzed reaction with thiols, whereas (Z)-alkenyl halides gave alkynes under the same reaction conditions. Aryl halides were also transformed into aryl sulfides using the same reagent system.

Highly regioselective thioformylation of terminal acetylenes with thiols and carbon monoxide has been developed by the use of rhodium(I) complexes as the catalyst: formyl and thio groups are introduced into the terminal and inner positions of acetylenes, respectively. The thioformylation is performed in the presence of a catalytic amount of rhodium(I) complexes, such as RhH(CO)(PPh3)3, RhCl(PPh3)3, and RhCl(CO)(PPh3)2, under the pressure of CO (3 MPa) at 120°C in CH3CN to provide β-thio-α,β-unsaturated aldehydes in good yields. This thioformylation can be applied to a variety of terminal acetylenes and aromatic thiols. A mechanistic proposal includes the formation of the rhodium sulfide complex as the key species.

A novel carbonylative addition of thiols (RSH) to terminal acetylenes (R′-C≡CH) takes place successfully in the presence of platinum catalysts under the pressure of carbon monoxide, providing α,β-unsaturated thioesters (R′-C(C(O)SR)=CH2) in good yields regioselectively. This 'hydrothiocarbonylation' reaction of acetylenes may include the formation of the platinum sulfide complex as key species.

The radical reaction of benzenethiol with alkynes 1a-o carried out at 154 °C affords a mixture of thiol/alkyne adduct 3 and benzothiophene 5, deriving from vinyl radical intermediates 2 through hydrogen abstraction and 5-(π-endo)(orthocyclization onto the
One-pot dialkylation of allylphenylsulfide induced by aminoalkoxides- activated NaNH2. Application to the synthesis of unsymmetrical ketones
Choppin, Sabine,Gros, Philippe,Fort, Yves
, p. 9261 - 9268 (2007/10/03)
It is shown that the activation of NaNH2 by sodium aminoalkoxides, leading to new superbases, induced an efficient one-pot dialkylation of allylphenylsulfide. The regioselectivity of the reaction (α,α' vs α,γ) was found as strongly dependent on the nature of the alkyl halide. As an application, α,γ dialkylated products were efficiently converted Into the corresponding unsymmetrical ketones.

The reduction of dithiocarbonates or thiocarbonates by n-Bu3SnH-Et3B easily gives the corresponding hydrocarbons.Application of a new method in the conversion of carbonyl compounds into olefins is also described.

A series of thiiranes react with benzyne to provide an efficient synthesis of phenyl vinyl sulfides.The reaction is stereospecific, thus producing cis-(phenylthio)-stilbene from cis-2,3-diphenylthiirane and trans-(phenylthio)stilbene from trans-2,3-diphen
