excellent Michael-acceptor character of the terminal sp2carbon center and form a stabilized iodonium ylide intermediate first. After a proton transfer step, the iodonium part attached to the sp3carbon center could act as a super leaving group and make the carbon atom more electrophilic to accept a...
Various cinnamate derivatives were tested as inducers for reduction of C–C double bonds in Acetobacterium woodii. The double bond and a phenyl ring were essential for induction, since crotonate and hydrocaffeate were ineffective as inducers whereas cinnamate derivatives were effective. Induction was ...
结果1 题目 The groups that consists of oxygen and carbon joined by a double bond is called the carbonyl group. If the carbonyl group is at the end of the molecular skeleton it is called a(n) 相关知识点: 试题来源: 解析 aldehyde. 反馈 收藏 ...
(III) that would otherwise disproportionate. Thus, rather than the arene being the functional group focus, here it is overtly performing a role as an ancillary, facilitating ligand to stabilise another metal-ligand functional unit. These ‘two-dimensional’ polyuranium complexes also demonstrate that...
A survey of carbon–carbon double bond lengths in transition metal vinyl complexes reveals a number of complexes with surprisingly short C C bonds. Accurate calculations with restricted Hartree–Fock (RHF) and density functional theory (DFT) methods on three examples with extremely short C C double...
have seen the preparation of π systems containing novel (p-p)π bonds between carbon and elements from the third, fourth, and fifth Main Groups of the Periodic Table; most of these compounds are predicted to be incapable of existence according to the classical concepts of the double bond. ...
