Synthesis and (spectro)electrochemistry of mixedvalent diferrocenyl–dihydrothiopyran derivatives
(Royal Society of Chemistry, 2015-02-20)
Three novel diferrocenyl complexes were prepared and characterised. 2,2-Diferrocenyl-4,5-dimethyl-
3,6-dihydro-2H-thiopyran (1, sulphide) was accessible by the hetero-Diels–Alder reaction of diferrocenyl
thioketone with ...
On the strong difference in reactivity of acyclic and cyclic diazodiketones with thioketones: experimental results and quantum-chemical interpretation
(Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2015-04-20)
The 1,3-dipolar cycloaddition of acyclic 2-diazo-1,3-dicarbonyl compounds (DDC) and thioketones preferably occurs with Z,Econformers
and leads to the formation of transient thiocarbonyl ylides in two stages. The ...

Hetero-Diels–Alder reactions of hetaryl and aryl thioketones with acetylenic dienophiles
(Beilstein Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2015-04-28)
Selected hetaryl and aryl thioketones react with acetylenecarboxylates under thermal conditions in the presence of LiClO4 or, alternatively,
under high-pressure conditions (5 kbar) at room temperature yielding thiopyran ...
Matrix isolation and spectroscopic properties of the methylsulfinyl radical CH3(O)S˙
(The Royal Society of Chemistry, 2013-08-15)
The atmospherically highly relevant methylsulfinyl radical CH3(O)S˙ was generated thermally under flash pyrolysis conditions and isolated in Ar matrices at 10 K; the allyl radical is a byproduct. CH3(O)S˙ and its D3- and ...
Application of diethyl ethynylphosphonate to the synthesis of 3‐phosphonylated β‐lactams via the Kinugasa reaction
(ARKAT USA, 2017)
The easily available diethyl ethynylphosphonate reacts with diverse aldonitrones under Kinugasa reaction
conditions at room temperature, providing 3‐phosphonylated β‐lactams in good yields. In all cases, the
reaction ...
