Cupric cyanide represents an amorphous yellow powder insoluble in water. It is used in organic synthesis as the catalyst. Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria.

Trichloroisocyanuric acid (1,3,5-trichloro-1,3,5-triazine-2,4,6(1H,3H,5H)-tri-one or TCCA) is an N-halo compound which has been known since 1902. It has been used primarily as a disinfectant in swimming pools and water treatment as bleaching agent and bactericide. Recently, TCCA has become attractive candidate as a homogeneous catalyst in organic transformations due to its lack of volatility, commercial availability, low cost and ease of handling. And is also used as a bleaching agent in the textile industry
