6.8Alkyl halides Analkyl halideis another name for a halogen-substituted alkane. The carbon atom, which is bonded to the halogen atom, has sp3hybridized bonding orbitals and exhibits atetrahedral shape. Due toelectronegativitydifferences between the carbon and halogen atoms, the σcovalent bondbetween...
Scheme 2. Coupling of aryl halides with aliphatic alcohols in the presence of BINAM–CuI catalyst. An efficient O-arylation of phenols and aliphatic alcohols with aryl halides has been developed by the use of an air-stable copper(I) complex 12 as the catalyst (Scheme 3).24 A variety of ...
