Benzene reduction by molecular complexes remains a considerable synthetic challenge, and typically requires harsh reaction conditions involving group I metals. Now it has been shown that a highly polar organometallic samarium alkyl complex enables the reduction of benzene to its tetra-anion without the ...

After more than 150 years since the Kekule's conceptualization of the benzene structure, this small hexagonal hydrocarbon indubitably remains the most prototypical example of aromaticity. Recent developments revealed that aromaticity is not limited by canonical carbon, hydrogen, or nearby elements but ...
摘要:The new acyclic tetraoxime ligand H _4L ~1, having two allyl groups at the terminal benzene rings, was designed and synthesized. The ligand H _4L ~1 was converted to five kinds of the trinuclear complexes, L ~1Zn _3(OAc) _2, L ~1Zn _2La(OAc) 3, L ~1Zn _2Ca(OAc) ...
Malatesta and Cariello14 have re-ported the similar reaction: These zerovalent platinum compounds are soluble in benzene and chloro-form, but only slightly so in alcohols. Surprisingly, they are stable in the air. If one does not use an excess ofligand in the preparation, Pt(PRa)a is ...
