Six new oxo-centered triruthenium complexes with NCS − or NO 2 − as a terminal ligand [Ru 3 O(CH 3 CO 2 ) 6 (NCS)(L) 2 ] L = 4-dimethylaminopyridine (dmap) ( 1 ); L = pyridine (py) ( 2 )}, [PPh 4 ] 2 [Ru 3 O(CH 3 CO 2 ) 6 (NCS) 3 ] ( 3 ), [PPh 4 ] 2 [Ru 3 O(CH 3 CO 2 ) 6 (CO)(NCS) 2 ] ( 4 ), and [Ru 3 O(CH 3 CO 2 ) 6 (NO 2 )(L) 2 ] L = dmap ( 5 ); L = py ( 6 )} were prepared. The thiocyanate is coordinated
摘要六种新的以NCS-或NO 2-为末端配体的以氧为中心的三钌络合物[Ru 3 O(CH 3 CO 2)6(NCS)(L)2] L = 4-二甲基氨基吡啶(dmap)(1) ; L =吡啶(py)(2)},[PPh 4] 2 [Ru 3 O(CH 3 CO 2)6(NCS)3](3),[PPh 4] 2 [Ru 3 O(CH 3 CO 2) )6(CO)(NCS)2](4),和[Ru 3 O(CH 3 CO 2)6(NO 2)(L)2] L = dmap(5); 准备L = py(6)}。对于所有NCS-配合物,硫氰酸盐均通过N原子配位。尽管获得的dmap配合物5为具有N坐标亚硝酸盐的单一异构体,但获得的py配合物6为涉及亚硝酸盐配位模式的两种异构体的混合物。连接异构化太快以至于不能分离这些异构体,并且通过1 H NMR上的饱和转移技术进行了证实。这些化合物表现出可逆的氧化还原行为,并

The present invention aims to provide a means by which a cured product to be obtained has a low dielectric loss tangent and higher heat resistance. Specifically, provided are an active ester compound represented by chemical formula (1):
(where in chemical formula (1), Ar
1
is a substituted or unsubstituted first aromatic ring group, and each Ar
2
is independently a substituted or unsubstituted second aromatic ring group, in which at least one of Ar
1
and Ar
2
has an unsaturated bond-containing substituent, and n is an integer of 2 or 3), a curable composition containing the active ester compound, and a cured product thereof.
cation radical salts with tetrahedrally coordinated zinc(II) complex anions were obtained by electrocrystallization; most of them were produced via the additional reaction of Lewis-basic cyano-containing anions [N(CN)2–, C(CN)3–, and Au(CN)2–] with ZnX2 (X = Cl–, Br–, and SCN–) that occurred during electrocrystallization. On the basis of the charge and arrangement of ET molecules, these salts were predominantly

The present invention provides a curable resin composition that can provide a cured material excellent in insulation reliability while maintaining adhesiveness and provide a composition for forming a solder resist, a dry film and a printed wiring board, a laminate having a resin insulating layer excellent in insulation reliability while maintaining adhesiveness, a dry film for forming this and a process for preparing a laminate using the dry film. The curable resin composition contains (A) an imidazole-isocyanate adduct, (B) a carboxyl group-containing resin and (C) a thermosetting resin. The above laminate has a substrate and a plurality of resin insulating layers formed on the substrate, in which one of the plural resin insulating layers in contact with the substrate is a layer formed of the curable resin composition.
The Lewis superacid bis(perchlorocatecholato)silane serves as a binding platform for weak anionic donors, providing the first characterized anionic bromido, iodido, formato, acetato, triflato, and sulfato silicates. This set allows to evaluate the structural and electronic perturbation of silicon species and substantiates their role in Lewisbasecatalysis.
