壮观的游行

Organic Syntheses via Organometallics,less, in the course of these experiments they discovered catalytic hydrogenation. More than 60 years later we were able to realize the original idea of Sabatier in part when we managed to prepare first Ni[COD]..; and later Ni[C.H.]... Numerous complexes of nickel(0) have since been synthesized.

摸索

,Highly Reactive π-Arene Iron Complexes and their use in Stoichiometric and Catalytic Cyclic Additiometal atom ligand cocondensation techniques [1]. This allows one to do the cyclic additions at low temperatures, which should have a considerable impact on the direction and selectivity of the reactions.

流出

Metal-Induced Dimerisations of Cyclic Diacetylenes,nfluence on the chain length. The separation between the bonding (π..) and antibonding (π..) linear combination of the “in plane” π-MO’s of two acetylene moieties is diminished if we connect them with an ethano bridge as in . (see Figure 1 left).

就职

Organometallic Transformations via C-H Bond Activation, complexes described include (C.Me.)Rh(PMe.)(R)H (R = H, CH., Ph), (C.Me.)Rh(CNR)., RhCl(PR.).(CNR’), Fe(PMe.).(CNR)., and Ru(dmpe).(naphthyl)H. Both aldimines and indoles are formed catalytically with these complexes.

荧光

Remote Functionalization of Carbon-Hydrogen and Carbon-Carbon Bonds by Bare Transition Metal Ions if the molecule (see, for example, the enzymatic conversion of stearic to oleic acid. Scheme 1), only a few cases in solution chemistry are reported [1] where a similar principle seems to be operative.

善于骗人

Ironcarbonyl Complexes of Exocyclic Polyenes. The Tricarbonyl(1,3-Diene)Iron Moiety as Remote Substugh electronic effects. Depending on the electron demand of the reaction, the remote (diene)Fe(CO). group can act either as an electron-withdrawing substituent (inductive effect due to its permanent dipole) or as an electron-releasing substituent due to its polarisability.

整顿

New Properties of Reagents by Complexation of Carbanions on Transition-Metals: Which Metal is in Eaonic residue is coordinated to a transition-metal according to Scheme 1, causing serious changes in the properties of the alkyl derivatives. The changes, stated in scheme 1, have proved to be useful in organic synthesis.
