Exploiting Aryl Mesylates and Tosylates in Catalytic Mono-α-arylation of Aryl- and Heteroarylketones

Organic Letters, 2016
The first general palladium catalyst for the catalytic mono-α-arylation of aryl- and heteroarylketones with aryl mesylates and tosylates is described. The newly developed indolyl-derived phosphine ligand L7 has been identified to promote this reaction efficiently.

Iron-Catalyzed Coupling of Aryl Sulfamates and Aryl/Vinyl Tosylates with Aryl Grignards

Organic Letters, 2014
The 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.

SYNTHESIS OF ARYL THIOCYANATES FROM ARYL ALKYL SULPHIDES. CONVERSION OF UNACTIVATED ARYL HALIDES INTO ARYL THIOCYANATES

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, 1979
1. 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, 2002
Pentaarylantimony 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.

Photocatalytic Reductive Borylation, Phosphonation, Sulfurization, and Selenization of Aryl Iodides to Access Aryl Borates, Aryl Phosphates, Aryl Sulfides, and Aryl Selenides

Asian Journal of Organic Chemistry
Abstract A simple photoinduced radical borylation, phosphonation, sulfurization and selenization of various aryl iodides to construct the structurally diverse C‐B/P/S/Se bonds has been developed. Using HCO 2 Na as the reductant, a wide range of aryl iodides including the ...
