An efficient and high-yielding cross-coupling reaction of various primary, secondary, and tertiary alkyl chlorides with aryl Grignard reagents was achieved by using catalytic amounts of N-heterocyclic carbene ligands and iron salts. This reaction is a simple and efficient arylation method having applicability to a wide range of industrially abundant chloroalkanes, including polychloroalkanes, which are challenging substrates under conventional cross-coupling conditions.
Boron Tris(triflate) Catalyzed Adamantylation of Benzene and Toluene with 1- and 2-Haloadamantanes and Adamantanoyl Chlorides. Isomerization of Phenyl- and Tolyladamantanes

Boron tris(triflate) catalyzed adamantylation of benzene and toluene was studied with isomeric 1- and 2-haloadamantanes.The alkylations give 1- and 2-phenyl- and isomeric tolyladamantanes in varying ratios.Interconversion of isomeric 2-phenyl(tolyl)adamantanes into the corresponding 1-phenyl(tolyl)adamantanes was observed through intermolecular isomerization involving adamantyl cations and adamantane, which is formed in significant amount in all the reactions.Decarbonylative alkylation of aromatics with adamantanoyl chlorides was also investigated.Adamantanoylated aromatics were formed only in very low amounts, the major product being adamantylated aromatics in accord with extensive decarbonylation of the adamantanoyl cations.The mechanism of the studies adamantylations was further substantiated by studying the boron tris(triflate) catalyzed isomerization of 1- and 2-aryladamantanes under comparable conditions.
Preparation of 1,3-Functionalized Adamantanes by Lewis Acid Catalyzed Electrophilic Cyclization of 7-Methylenebicyclononan-3-one in the Presence of ?- and N-Nucleophiles

Preparation of 1,3-difunctionalized adamantane derivatives from 7-methylenebicyclononane-3-one (1) in the presence of nucleophiles under Lewis acid catalysis is described.Reaction of 1 with benzene using a variety of Lewis acid catalysts gave 1,3-d
Direct Clay-Catalyzed Friedel-Crafts Arylation and Chlorination of the Hydrocarbon Adamantane
Chalais, Stephane,Cornelis, Andre,Gerstmans, Andre,Kolodziejski, Waclaw,Laszlo, Pierre,et al.
, p. 1196 - 1203 (2007/10/02)
Multiple chlorinations and arylations at the tertiary positions of adamantane are promoted by FeCl3-doped K10 montmorillonite in CCl4 or in aromatic solvents.The process, remarkably easy implement, can be tailored to selective formation of monosubstituted 1-adamantyl derivatives or 1,3-disubstituted adamantanes.The process achieves alkylation at the meta- and para-positions of toluene leading to a purely statistical distribution and displays no substrate specificity in competition experiments between toluene and benzene.
REACTIONS OF ADAMANTYL NITRATES WITH AROMATIC COMPOUNDS.
Moiseev, I. K.,Doroshenko, R. I.
, p. 1067 - 1069 (2007/10/02)
It has been shown to be possible to use adamantyl nitrates in the synthesis of mono- and diaryladamantanes.The effects of substituents and the acidity of the medium on the yields of reaction products have been studied.
