A metal-free, photocatalyst-free, photochemical system was developed for the direct alkylation of thiophenols via electron donor-acceptor (EDA) complexes (KEDA = 145 M-1) between two reactants, N-hydroxyphthalimide esters as acceptors and thiophenol anions as donors, in the presence of a tertiary amine. The EDA complexes in the reaction system have a broad range of visible-light absorption (400-650 nm) and can trigger the reaction effectively under sunlight.

A nickel-catalyzed decarbonylation of carboxylic acids cross-coupling protocol has been developed for the straightforward C?S(Se) bond formation. This reaction is promoted by a commercially-available, user-friendly, inexpensive, air and moisture-stable nickel precatalyst. Various carboxylic acids and a wide range of aryl dichalcogenide substrates were tolerated in this process which afforded products in good to excellent yields. In addition, the present reaction can be conducted on gram scale in good yield.

A nickel-catalyzed aryl thioether metathesis has been developed to access high-value thioethers. 1,2-Bis(dicyclohexylphosphino)ethane (dcype) is essential to promote this highly functional-group-tolerant reaction. Furthermore, synthetically challenging macrocycles could be obtained in good yield in an unusual example of ring-closing metathesis that does not involve alkene bonds. In-depth organometallic studies support a reversible Ni0/NiII pathway to product formation. Overall, this work not only provides a more sustainable alternative to previous catalytic systems based on Pd, but also presents new applications and mechanistic information that are highly relevant to the further development and application of unusual single-bond metathesis reactions.

An iodine-promoted regioselective sulfenylation/deoxygenation/aromatization reaction of 1-tetralones with disulfides has been developed. This process could be modified to synthesize 2-naphthyl thioethers and 1-naphthyl thioethers in moderate to excellent

Ether-exchange reaction of alkyl aryl ethers with alcohols and thiols via the cleavage of the C(sp2)-O bond is described. Bi(OTf)3 was found to be a most effective catalyst, and etherification of fused-aromatic ethers proceeded efficiently. Monitoring of reactions revealed conceptually new transether-ification between two different ethers, which can be regarded as single-bond metathesis under the same reaction conditions.
Bismuth(III)-catalyzed dehydrative etherification and thioetherification of phenolic hydroxy groups
Murai, Masahito,Origuchi, Kazuki,Takai, Kazuhiko
supporting information, p. 3828 - 3831 (2014/08/05)
Use of a bismuth catalyst allowed efficient dehydrative substitution of phenolic hydroxy groups with alcohols and thiols to form C-O and C-S bonds. The reaction required equimolar amounts of two readily available substrates that generated H2O as the only byproduct. The relatively mild reaction conditions were compatible with the functional groups selected, and provided excellent chemoselectivity.
