Step by step solution

01

Heck Reaction

The Heck reaction is a cross-coupling reaction involving a vinyl or aryl halide with an unsaturated compound, catalyzed by palladium (II) acetate(PdOAc2)in the presence of a base such as triethyl amine (Et3N)and triaryl phosphine (Po-tolyl3)to form a highly substituted alkene.

c.

Bi-aryls, compounds containing two aromatic rings joined by a C-C bond, can often be efficiently made by two different Suzuki couplings; that is, either aromatic ring can be used to form the organoborane needed for coupling. In some cases, however, only one route is possible. With this in mind, synthesize each of the following bi-aryls using benzene as the starting material for each aromatic ring. When more than one route is possible, draw both of them. You may use any required organic or inorganic reagents.
