isomeric form. The 1H n.m.r. spectra of both the isomers of the cobalt(III) complexes indicated a trans configuration. An electric polarization study of nickel(II) complexes also suggested that both isomericcomplexes had the trans configuration and that they were linkage isomers containing ligand isomers A and B. The participation of the furan oxygen in co-ordination was indicated in the A isomeric
合成了N-糠基水杨醛亚胺与Co III,Ni II Cu II和Pd II的配体异构体配合物(OC 4 H 3 CH 2 N CHPhOH,A和OC 4 H 3 CH NCH 2 PhOH,B)。异构现象的性质由偶氮甲碱基团,C N基团频率和电极化的1 H nmr光谱数据表征。与V IV O,Cr III,Mn II,Fe III,Pt II,Be的配合物II和Zn II以A异构形式获得。钴(III)配合物的两种异构体的1 H nmr光谱表明是反式构型。镍(II)配合物的电极化研究还表明,两种异构体均具有反式构型,并且它们都是包含配体异构体A和B的键合异构体。呋喃氧以配体形式参与了配位反应。与Pd II和Zn II的配合物。紫外光谱补充了异构体的表征。

We firstly describe a catalyst-free direct ring-opening of cyclic aldimines with abundant aliphaticprimaryamines to construct o-hydroxy schiff bases under mild reaction conditions. The corresponding products were generated in good to excellent yields (80–99%). In addition, a gram-scale reaction and further application of the reaction strategy were performed.
