IRON BISPHENOLATE COMPLEXES AND METHODS OF USE AND SYNTHESIS THEREOF

The present application, relates to iron bisphenolate complexes and methods of use and synthesis thereof. The iron complexes are prepared from tridentate or tetradentate ligands of Formula I: wherein R1 and R2 are as defined herein. Also provided are methods and processes of using the iron bisphenolate complexes as catalysts in cross-coupling reactions and in controlled radical polymerizations.

Structure and C-C cross-coupling reactivity of iron(III) complexes of halogenated amine-bis(phenolate) ligands

The preparation of tetradentate amine-bis(phenol) proligands with dichloro and difluoro substituted phenol groups and their reaction with FeX3 (X = Cl or Br) is described. The compounds, 2-pyridylamino-N,N-bis(2-methylene- 4,6-dichlorophenol), H2[L1]; 2-pyridylamino-N,N-bis(2- methylene-4,6-difluorophenol), H2[L2]; dimethylaminoethylamino-N,N-bis(2-methylene-4,6-dichlorophenol), H 2[L3]; 2-tetrahydrofurfuryl-N,N-bis(2-methylene-4,6- dichlorophenol), H2[L4]; and methoxyethylamino-N,N-bis(2- methylene-4,6-dichlorophenol), H2[L5] were prepared in aqueous medium and obtained as white powders in good to excellent yield. Ten new iron(III) halide complexes supported by these tetradentate ligands are reported. Representative single crystal X-ray diffraction structures were obtained for H2[L1] and a water adduct of the iron(III) complex, aquachloro{2-pyridylamino-N,N-bis(2-methylene-4,6-dichlorophenolato)} iron(III), 2·H2O. The structure of the proligand H 2[L1] shows intramolecular hydrogen bonding. In the solid-state structure, the iron complex exhibits intermolecular hydrogen bonding between the water ligand and the phenolate oxygen of a neighbouring complex. The anhydrous complexes were studied for catalytic activity towards C-C cross-coupling of Grignard reagent nucleophiles with alkyl halide electrophiles.

Thermally Initiated Reactions of Allyl sec-Butyl Sulfone. Observation of a -Allylic Rearrangement

Allyl alkyl sulfones undergo thermal rearrangement to afford alkenes and sulfur dioxide.Details of the mechanism were investigated by studying the thermolysis of allyl sec-butyl sulfone (1).Gas-phase pyrolysis of 1 afforded propene, butenes, isopentane, 1,5-hexadiene, and 4-methyl-1-hexene (3) as major products.The activation energy for the process was determined to be 41.4 +/- 2.3 kcal/mol in the temperature range 220-272 deg C.As the temperature for the pyrolysis was lowered from 560 deg C to 192 deg C, the ratio of 1,5-hexadiene to 4-methyl-1-hexene (3) changed from 3.89 to 0.04.Furthermore, pyrolysis of allyl-α,α-d2 sec-butyl sulfone (1-d2) at 580 deg C gave a 1:1 mixture of 1,1- and 3,3-dideuterio-4-methyl-1-hexene, but the ratio changed to 1:4.2 at 278 deg C.Control experiments illustrated that at least some of the observed deuterium scrambling was due to the existence of a -allylic rearrangement within the starting sulfone.Pyrolysis of optically active allyl sec-butyl sulfone ((R)-1*) at 580 deg C and 278 deg C afforded racemic 4-methyl-1-hexene (3).A control experiment demonstrated that recovered sulfone was not racemized.These results suggest that the rearrangement changes from free radical to a more selective and perhaps concerted mechanism as the temperature for the pyrolysis is lowered.Taking this factor into account, it was possible to convert the observed rate constants into contribution from the two competing pathways, kc and kr.In this way, it was determined that the activation energies for the concerted and free radical pathways were 39.6 (log A = 11.8) and 48.1 kcal/mol (log A = 14.9), respectively.Kinetic simulation provided a good fit to the existing data and allowed a determination of the rate constant for the -allylic rearrangement; good agreement with the existing literature value was obtained.

CYCLIZATION OF C7-ALKANES OVER Pt BLACK CATALYST

C6-and C5-cyclization of heptane isomers (and also, olefin formation as a related process) over Pt-black have been studied in pulse and circulation systems.Hydrogendeficient conditions favour aromatization, via presumably terminal olefins.C5-Cyclization in the presence of more hydrogen is accompanied by internal olefin formation.Relative reactivities of all heptane isomers have been measured; this shows that cyclization is easier between terminal methyl groups.Optimum hydrogen pressures for both types of cyclization have been determined (and compared with hydrogenolysis, too).Earlier mechanism suggestion for aromatization and cyclopentane formation have been confirmed; the distinction between two types of bond shift mechanisms producing aromatics (from substituted pentanes) and saturated isomers, respectively, has recieved additional support facilitating the identification of these two reactions with mechanisms proposed in the literature.

Nickel-catalyzed Asymmetric Alkylation of Some Chiral and Achiral Allylic Alcohols

(-)(R)-1,2-bis(Diphenylphosphino)-1-phenylethane(II) chloride was found to catalyze the asymmetric alkylation of some chiral and achiral allylic alcohols with Grignard reagents, leading to the formation of optically active olefins.Enantiomer discrimination of the substrate takes place in the alkylation of chiral allylic alcohols.

PREPARATION OF HIGHER ADAMANTANE HOMOLOGUES BY REACTION OF ADAMANTAN-1-OL WITH HEPTENES IN SULFURIC ACID
