Phenyldithiocarbamates: Efficient Sulfuration Reagents in the Chan–Lam Coupling Reaction
Cheng, Yu,Liu, Xing,Dong, Zhi-Bing
, p. 815 - 820 (2018/02/21)
The Chan–Lam coupling reaction starting from phenyldithiocarbamates and phenylboronic acids is reported. To avoid using the volatile, hazardous, and foul-smelling thiols, which are sometimes expensive and not sufficiently available, phenyldithiocarbamates can be employed. They are demonstrated to be good sulfuration reagents in the Chan–Lam coupling to prepare biaryl sulfides. By using this protocol, dithiocarbamate substrates with a wide range of functional groups including electron-rich and electron-deficient ones are explored to obtain the desired substituted biaryl sulfides smoothly. This method is ligand-free, has a broad substrate scope, enables good yields, and is easy to perform. It provides a facile and convenient preparation of biaryl sulfides.

An efficient method for constructing a 10-membered carbocycle with an oxygen bridge has been developed on the basis of a formal [6+4] cycloaddition reaction. Under the influence of EtAlCl2, a dicobalt hexacarbonyl acetylene complex possessing a
Synthesis of polysubstituted 3-thiofurans by regiospecific mono-ipso-substitution and ortho-metallation from 3,4-dibromofuran
Alvarez-Ibarra, Carlos,Quiroga, Maria L.,Toledano, Emilio
, p. 4065 - 4078 (2007/10/03)
The synthetic potential of 3,4-dibromofuran has been assessed by its conversion into 3,4-disubstituted furans via mono-S-ipso-substitution. The ability of 3-methylthio and 3-phenylthio substituents for directing the metallation at position α-relative to the substituent has allowed the regiospecific alkylation. It provides a straightforward approach to several 3-monothiosubstituted furans which are receiving increasing interest as odour and flavour chemicals.
