Triphenylarsenic oxide

ISOCIANATO de METILO (Spanish) (624-83-9) Forms explosive mixture with air (flash point 0°F/- 18°C). Reacts slowly with water violently with warm water or steam, forming carbon dioxide and heat. Decomposes above 100°F/38 C. Violent reaction with acetaldehyde, amines, alcohols, acids, alkalis, strong oxidizers. Unless inhibited, can produce unstable peroxides contact with iron, tin, copper, or salts of these elements, or with certain catalysts such as triphenylarsenic oxide, triethylphosphine, or tributyltin oxide, or elevated temperatures may cause polymerization. Incompatible with glycols, amides, ammonia, caprolactam. Attacks some plastics, rubber, or coatings. The uninhibited monomer vapor may block vents and confined spaces by forming a solid polymer material. 

Triphenylarsenic oxide is formed in oxygen transfer reactions involving triphenylarsine and certain oxygen-containing compounds such as 1-pyrroline-l-oxides and thiolsulhnates 327, 328).
