Document Type and Number:
Japanese Patent JP2598963
Kind Code:
B2
Abstract:
PURPOSE:To readily obtain the subject compound useful as an infrared ray absorber, etc., in a simple step using an inexpensive raw material, by reacting a tropolone-based compound with phosphorus pentasulfide and then reacting the resultant reaction product with polyvalent metallic ions. CONSTITUTION:A tropolone-based compound (preferably tropolone, etc.) is initially reacted with phosphorus pentasulfide so as to provide preferably 1:1-1:1.25 molar ratio of the former:latter. The resultant reaction product is then reacted with polyvalent metallic ions to afford the objective compound. The tropolone-based compound is preferably reacted with the phosphorus pentasulfide in dioxane in a refluxing state for 2-4hr and then a polyvalent metallic ion compound in an amount of 0.5-0.7mol based on 1mol tropolone- based compound is added to the reaction system and reacted in a refluxing state for 1-2.5hr. Furthermore, a compound expressed by the formula (R is alkyl; M is polyvalent metal) in the objective compound is a novel substance.
