It can be oxidized to [Cp2Fe]+, and the increase of the oxidation state of the iron atom makes the electrons of the locene ring (Cp) flow to the metal, which hinders the electrophilic substitution reaction of the ring. Ferrocene is resistant to hydrogenation and does not react with ...
The product of the reaction between BF 3 and acetic anhydride has been shown to be 3,3,9,9-tetrafluoro-5,7-dimethyl-2,4,8,10-tetraoxa-3,9-diborabicyclo [4.4.0]deca-1,5,7-triene, the bis(boron difluoride)derivative of 伪-acetylacetoacetic acid (I). Acetoacetylferrocene reacts with ...

Friedel-Crafts reactionAcylationBlocking of the lone pair of electrons on the nitrogen in azaferrocene by co-ordination to the W(CO) 5 moiety enables Friedel-Crafts acylation of this heteroferrocene. W(CO) 5-complexes of azaferrocene and 2,5-dimethylazaferrocene react with acetyl- and propionyl...
The optically active 1,2-ferrocenediol and -diphosphane have been prepared by means of the stereospecific substitution reaction with the amino alcohol 13 on treatment with acetic anhydride, followed by hydrolysis or substitution with diphenylphosphane....
Chiral ferrocene tridentate ligand and preparation method thereof as well as application in asymmetric hydrogenation reaction catalysisThe invention discloses a ferrocene tridentate ligand which has planar chirality and carbon chirality and is shown in a structure general formula (I). In the formula (I...
diastereomer of the 1,2-acetoamido alcohol 8a with retention of configuration.Thus the ferrocenyl diacetate 3 has a "stronger arm",one side of the acetoxy group being selectively displaced by ammonia.The reaction mechanism of formation of a single isomer of acetoamido alcohol 8 will be ...
Mono-acylated ferrocene (acetylferrocene) was synthesized by this reaction with almost 100% selectivity.doi:10.1016/j.apcata.2007.05.023Martina BejblováStacey I. ZonesJi?í ?ejkaElsevier B.V.Applied Catalysis A GeneralMartina Bejblova,Stacey I Zones,Jiri Cejka. Highly selective synthesis of ...
scope revealed that the transposition of the substituents between the reaction partners can have a substantial effect on the yield of the coupling product in otherwise complementary reactions, which highlights the importance of the judicious choice of starting materials for this particular reaction.doi...
