| Abstract: | Abstract Aryldiazonium silica sulfates were employed as new and efficient reagents for Heck-type arylation reactions with styrene and
methyl acrylate. The reactions were carried out in an organic solvent, in the presence of Pd(OAc)2 as precatalyst without use of base and free ligand. The trans isomers of desired products, methyl cinnamates and stilbenes, were obtained with full conversion. Use of a catalytic amount
of Pd(OAc)2 produced the corresponding products in short reaction times and excellent yields. |
