Fries Reaction

An AICl3–ZnCl2 mixture supported on silica gel is found to be an efficient medium for the Fries rearrangement of acyloxybenzene or naphthalene derivatives in solvent-free conditions under microwave irradiation.

Efficient Catalyst

The development of a silica-promoted highly selective synthesis of 1,2 or 1,3-dithioethers via solvent-free one-pot tandem reactions of an allyl bromide with excess thiol at room temperature is described. The choice of silica gel, either pre-calcined or moistened with water, exhibited notable regioselectivity in the formation of dithioethers. Plausible mechanistic routes were explored and postulated.

In Situ Generation

A one-pot, multicomponent condensation reaction of phenols, aromatic aldehydes, and amides in the presence of catalytic amount of trityl chloride as a homogeneous organocatalyst under solvent-free condition to prepare amidoalkyl phenols has been reported. It is interesting that trityl chloride by in situ generation of trityl carbocation with inherent instability catalyzes the reaction.
