Visible Light-Induced Aerobic Epoxidation of α,β-Unsaturated Ketones Mediated by Amidines

An aerobic photoepoxidation of α,β-unsaturated ketones driven by visible light in the presence of tetramethylguanidine (3b), tetraphenylporphine (H2TPP), and molecular oxygen under mild conditions was revealed. The corresponding α,β-epoxy ketones were obtained in yields of up to 94% in 96 h. The reaction time was shortened to 4.6 h by flow synthesis. The mechanism related to singlet oxygen was supported by experiments and density functional theory (DFT) calculations.

Guanidines as a nitrogen source for direct conversion of epoxides to aziridines

Direct conversion of epoxides to aziridines was achieved with guanidines as a nitrogen source. Stereochemical inversion at the chiral centers of epoxides was observed without loss of optical purity.

Synthesis of primary amines and N-methylamines by the electrophilic amination of Grignard reagents with 2-imidazolidinone O-sulfonyloxime

2-Imidazolidinone O-sulfonyloxime reacts with various aryl and alkyl Grignard reagents as an electrophilic amination reagent, giving N-alkylated imines. The resulting imines are transformed to primary amines and N-methyl secondary amines by hydrolysis with CsOH and LiAlH4 reduction, respectively.

Aminosilylation of heterocumulenes and the intramolecular decomposition of their silyl-functionalized adducts

Heteroorganic amidosilanes are readily obtained by interaction of CO2, CS2 and other heterocumulenes with pentacoordinated diaminosilanes.A comparison is made with the corresponding reactions of tetracoordinated species.Decompositon of these bifunctional organosilanes gives 2-substituted ureido derivatives and base-stabilized low coordinated silicon species, seemingly by a unimolecular thermal β-elimination.
