MXm・Ln (II)
(式中、Mはビスマス、ガリウム、インジウム、希土類元素から選ばれる金属イオンを示す。Xはハロゲンアニオン、パーフルオロアルキルスルホナートアニオン、ビス(パーフルオロアルキルスルホニル)アミドアニオン、トリス(パーフルオロアルキルスルホニル)メチドアニオンから選ばれるアニオンを示す。Lは配位力のある中性分子を示す。mは金属Mの原子価数であり、nは0〜10の整数である。)
で表されるルイス酸の触媒量と反応させることによる、一般式(III)
また、一般式(I)において環Aは、単環もしくは縮合多環の芳香環基または複素芳香環基であり、それらの環を構成する原子には、1個以上の窒素原子(N)、酸素原子(O)またはイオウ原子(S)を含んでいてもよく、また環が反応に関与しない基で置換されていてもよい。ただし、これらの芳香環基または複素芳香環基は一般式(I)に示すように、プロピオン酸部位が直接結合した炭素原子に結合する2つの原子のうち少なくとも1つには水素原子が結合した炭素原子でなければならない。
MXm・Ln (II)
で表される金属化合物である。
一般式(II)において、Mは金属イオンであり、ビスマス、ガリウム、インジウム、及びスカンジウム、サマリウム、イッテルビウムなどの希土類元素から選ばれる。
また、アニオンXは、その共役酸が高い酸性度を示すものがよく、例えばハロゲンアニオン、パーフルオロアルキルスルホナートアニオン、ビス(パーフルオロアルキルスルホニル)アミドアニオン、トリス(パーフルオロアルキルスルホニル)メチドアニオンなどが挙げられる。
反応温度としては、あまりに低温では反応が有利な速度では進行せず、一方、あまりに高温では副反応が起こるとともに経済性も劣ることから、一般的には0〜350℃の範囲から選ばれ、好ましくは60〜280℃の範囲で実施される。
