| Outline of Final Research Achievements |
Direct synthesis of carboxylic-phosphinic mixed anhydrides has been achieved by treating carbon dioxide with
Recently,wereported the synthesis ofN-phosphine oxideN-phosphine oxide-substituted imidazolylidenes (PoxIms) that contain both nucleophilic carbene and electrophilic phosphorus moieties.This novel mixed anhydride was efficiently derivatized into an ester,anamide,and an unsymmetrical ketone via transformation into its corresponding imidazolium salt followed by adual substitution reaction. The presented work used well-designed multifunctional carbene reagents to establish anovel utility for carbon dioxide in organic synthesis.

| Academic Significance and Societal Importance of the Research Achievements |
地球温暖化は確実に進行しており、ここ数年の気候変動はその端緒に過ぎないと考えられる。この様な背景のもと我々科学者は地球温暖化ガスの削減に対して積極的に関与する事がもとめられている。本研究においては二酸化炭素の有効利用利用だけに留まる温暖化温暖化能が二酸化炭素の１万５千倍のフルオロホルムの有効利用にも役立つ新触媒の開発にもとりくんでいまｓ。
