scheme or table, p. 124 - 127 (2009/04/14)
A new route for the synthesis of linear and vinyl thioethers has been demonstrated using bare silica nanoparticle as catalyst at room temperature under solvent-free conditions. The catalyst can be reused up to six times without loss of catalytic activity.

We present here a clean, solvent-free hydrothiolation of alkynes using solid supported catalyst (Al2O3/KF). This efficient and improved method selectively furnishes the corresponding anti-Markovnikov vinyl sulfides in good to excellent yields. The method is applicable for aliphatic and aromatic thiols and the catalytic system can be re-used up to two times without previous treatment and with comparable activity.
Synthesis of Alkenes via Peterson Reaction
Ager, David J.
, p. 183 - 194 (2007/10/02)
The α-phenylthiosilanes (2) have been used to prepare the α-silyl anions (1) by reaction with lithium naphthalenide; subsequent condensation with a carbonyl compound gave the alkene (8) via the Peterson reaction.The α-phenylthiosilanes (2) were prepared from n,n-bis(phenylthio)acetals (4) by reaction with lithium naphthalenide and chlorotrimethylsilane.The n,n-bis(phenylthio)acetals (4) were obtained, in turn, from 1,1-bis(phenylthio)acetals (5) by anion formation with butyl-lithium-N,N,N',N'-tetramethylethylenediamine complex in hexane followed by reaction with an alkyl halide.The Peterson reaction was also used to prepare vinyl sulphides (9) and vinyl sulphones (13).
PREPARATION OF 1-ALKENYL PHENYL SULFIDES BY THE NICKEL(II)-COMPLEXES CATALYZED COUPLING REACTION OF 3-METHOXY-1-PHENYLTHIO-1-PROPENE WITH GRIGNARD REAGENTS
Sugimura, Hideyuki,Takei, Hisashi
, p. 1505 - 1508 (2007/10/02)
The reaction of on 3-methoxy-1-phenylthio-1-propene with aryl and primary alkyl Grignard reagents in the presence of nickel(II)-phosphine complex in benzene or toluene proceeded chemo- and regioselectively to give 1-alkenyl phenyl sulfides in high yields.
Phosphorus Tri-iodide (PI3), a Powerful Deoxygenating Agent
Denis, Jean Noel,Krief, Alain
, p. 544 - 545 (2007/10/02)
On reaction with PI3 sulphoxides, selenoxides, aldehyde oximes, and primary nitroalkanes are transformed to sulphides, selenides, and nitriles, respectively.
