Outline of Final Research Achievements	KMgF3 which is one of Fluoro-perovskite was developed as a new solid base catalyst by mechano-chemical technique. The KMgF3 prepared by a pulsar ball mill at high rotation rate, had superior catalytic activity for Knoevenagel condensation compared to several solid base catalysts and good reusability. The iron addition to KMgF3 under mechano-chemical step brought about the appearance of ferromagnetism, resulted in the development of magnetically separable solid base catalysts.

Academic Significance and Societal Importance of the Research Achievements	フルオロペロブスカイトの一つであるKMgF3を新たな固体塩基触媒材料として提案できた点は，学術的に意義があるだけでなく，塩基触媒反応プロセスの環境負荷の低減に貢献することが期待できる．一方で，触媒調製法として適用したメカノケミカル法が，KMgF3の触媒活性を増強するだけでなく，Feの添加により新たな性質として強磁性の付与をもたらすことを見いだしたことは，メカノケミカルの新たな可能性の創出につながったと考えることができる．
