Title:
METHOD FOR CATALYTICALLY ACTIVATING SILICATED NUCLEATING AGENT USING PHOSPHAZENE BASE
Document Type and Number:
Japanese Patent JP3864199
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing an intermediate for synthesizing a phosphazene base using an organic catalyst less harmful to the environment without using harmful heavy metals.
SOLUTION: H-Si, C-Si, O-Si and N-Si bonds of an organic silicated nucleating agent are activated by acting the phosphazene base to the organic silicated nucleating agent in an organic solvent. Substituted benzene derivatives and substituted aromatic hetero ring compounds which are intermediates for synthesizing medical products are synthesized by catalytically applying the mutual action to carry out nucleophilic substitution and nucleophilic addition reactions.
