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. Graphical abstract
