综合XAS、AP-XPS和理论计算结果,研究人员提出了双核Zn-O-Cr位点上ICEC的原子协同机制:催化循环是通过C2H6在Zn上的吸附引发的,然后通过断裂Zn-O-Cr键形成Zn-CH2-CH3和Cr-OH;随后发生β-C-H键的均裂,最后是C2H4解吸和Zn-Hδ−形成。在Zn-O-Cr位点的Cr上的C2H6活化对于第一个C-H断裂和β-C-H键解离具有...

In addition, a small amount of the disubstituted compound (CO) 3 Cr(CNCF 3 ) (CNCH 3 ) 2 ( 6 ) is obtained, which according to its spectroscopic data contains the CNCF 3 ligand and one CNCH 3 ligand in trans position. In the case of 7 , the trans isomer is the only product ...
The photochemistry of (η6-2,6-X2C5H3N)Cr(CO)3 was investigated both in low-temperature matrices (X = H or (CH3)3Si) and in room-temperature solution (X = H, CH3, or (CH3)3 Si). Room-temperature photolysis (λexc > 410 nm) in CO-saturated methanol or acetonitrile...

答案对的,原子量大的优先,一级原子相同的情况下比较二级原子,双键相当于连了两个相同的原子.不过命名的时候还要先搞清楚官能团的顺序,再看取代基的顺序
