Abstract. A facile and stereoselective synthesis of novel transmonosubstitutedbenzylseleno-β -lactams via Lewis acid mediated functionalization of -lactam carbocation equivalents with active aromatic and heterocyclic compounds (nucleophiles) is described. Detailed listing of the publications from — today. that solutions of “CH 3MgBr” in diethyl ether contain CH 3MgBr and (CH 3) 2Mg was obtained by Ashby and co-workers by means of 1H NMR spectroscopic measurements at °ons of “t-butylmagnesium chloride” in diethyl ether also were studied.8 The tendency of the halide substituents in the RMgX and MgX 2 species present in ethereal solution at equilibrium to formFile Size: KB. 4 Electrophilic Aromatic Bromination Benzene’s π electrons participate as a Lewis base in reactions with Lewis acids The product is formed by loss of a proton, which is replaced by bromine FeBr 3 is added as a catalyst to polarize the bromine reagent In the first step the π electrons act as a nucleophile toward Br 2 (in a complex with FeBr.

  The binder is used to strengthen the molds and cores and can be heat cured, catalytically cured, or cured with a combination of heat and a catalyst. One of the processes used in sand casting for making molds and cores is the cold-box process. In this process, a gaseous curing agent is passed through a compacted shaped mix to produce a cured.

Pd(II)-catalyzed intermolecular 1,2-aminooxygenation and 1,2-oxyamination of conjugated dienes have been developed.

The chemoselective preparation of a variety of 2-functionalized and 3-functionalized 1,4-benzoxazine derivatives was accomplished via the adjustment of a coordinating solvent. Oxygen was successfully used in this oxidative difunctionalization of by: A method of synthesizing 3-arylquinoxalin-2(1H)-ones using diaryliodonium tetrafluoroborates under mild conditions is described.

This protocol has a wide substrate scope and enables direct C–H functionalization. The synthetic potential of this coupling was explored using a range of readily accessible diaryliodonium salts and quinoxalin-2(1H) by:   1.

Values of the13C chemical shifts and13C spin-spin coupling constants have been obtained for 1,1-dicarbonyl-1,3-dienes and their valence isomers, the 2H-pyrans. Valence isomerization occurs only in the E isomers and is absent in the Z isomers with respect to the α,β-double bond of the 1,1-dicarbonyl-1,3-dienes.

In the 23rd book of the Iliad, Homer recounts that Achilles awarded a discus made of iron bloom to the victor in a discus-throwing competition. For many centuries in Europe and Old Russia iron was made by blooming.

Iron ore was reduced with wood charcoal in a furnace made in a pit; air was blown onto.
