Treating low reactivity alkylating agents in the vapor phase with catalysts converts the low reactivity alkylating agents to high reactivity alkylating agents. The alkylating agents are useful in synthesis of alkyl aromatics with Lewis acid catalysts.

Catalytic process for making high reactivity alkylating agents and

Aliphatic hydrocarbyl-substituted aromatic amines are prepared by reacting an aromatic amine and an aliphatic hydrocarbylating agent, such as an olefin, in the presence of a heteropolyacid catalyst such as Cs.sub.2.5 H.sub.0.5 PW.sub.12 O.sub.40, for a period of time and at a temperature sufficient to permit reaction.

Alkylation of aromatic amines using a heterpoly catalyst

Hydrocarbyl-substituted amides can be prepared in a catalyzed Ritter reaction by contacting a nitrile with a hydrocarbylating agent, in the presence of an acidified clay as the catalyst, under conditions conducive to the formation of the hydrocarbyl-substituted amide.

Process for the preparation of N-hydrocarbyl-substituted amides via the

Hydrocarbyl-substituted amides are prepared by a process comprising contacting a nitrile with a hydrocarbylating agent, such as an alkylating agent, in the presence of a catalyst comprising a heteropolyacid or salt thereof.
