Palladium-Catalyzed N-Arylation of Sulfoximines with Aryl Bromides and Aryl Iodides
The Journal of Organic Chemistry, 1999Various N-arylated sulfoximines have been synthesized in high yield by a direct approach which is based on a palladium-catalyzed cross-coupling strategy. Aryl bromides of variable substitution pattern were found to be the most effective coupling partners, whereas aryl iodides showed a nonpredictable behavior requiring lithium or silver salts as ...

Efficient Copper-Catalyzed N-Arylation of Sulfoximines with Aryl Iodides and Aryl Bromides
The Journal of Organic Chemistry, 2005Two simple and inexpensive systems for copper-catalyzed N-arylations of sulfoximines with aryl bromides and aryl iodides have been developed. Using 10 mol % of a copper(I) salt in combination with 20 mol % of a 1,2-diamine and Cs2CO3 provides N-arylated sulfoximines in high yields. Various functional groups and heteroatoms are tolerated.

Iron-Catalyzed Coupling of Aryl Sulfamates and Aryl/Vinyl Tosylates with Aryl Grignards
Organic Letters, 2014The iron-catalyzed coupling of aryl sulfamates and tosylates with aryl Grignard reagents is reported for the first time. The methodology employs air-stable, low-cost FeF3·3H2O and the N-heterocyclic carbene ligand IPr·HCl as the preligand to form a long-lived catalyst upon treatment with aryl Grignards.

Phosphorus and Sulfur and the Related Elements, 1983
Abstract Aryl alkyl sulphides, easily obtained from aryl halides, can be selectively dealkylated in HMPA by treatment with sodium, sodium methanethiolate or sodium methoxide. The resulting solutions, containing the sodium arenethiolates, when treated with BrCN or ICN, afford the corresponding aryl thiocyanates in moderate to good yields.

Photolysis of aryl formates and aryl acetates
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19791. The yields of the phenols during the photolysis of a number of aryl formates and aryl acetates were determined. 2. The aroxyl radicals that are obtained during the photolysis of aryl formates and aryl acetates were recorded by the pulse photolysis method. 3. The photodissociation of aryl formates and aryl acetates proceeds

Arylation of Aryl- and Diarylbismuth Arenesulfonates with Pentaarylantimony
Russian Journal of General Chemistry, 2002Pentaarylantimony Ar3Sb (Ar = Ph, p-Tol) arylates diarylbismuth arylsulfonates Ar2BiOSO2Ar' (Ar' = C6H4Me-4; C6H3Me2-2,4, C6H3Me2-2,5) in ether at 20°C (48 h) to form triarylbismuth in yields of up to 95%. The second reaction product is tetraarylantimony arenesulfonate.
