Various 2-substituted 1,3-dithiolan-2-ylium perchlorates (1) were prepared by the reaction of 1,2-ethanedithiol with acyl chlorides in the presence of perchloric acid.Treatments of 1 with triethylamine gave 2-alkylidene-1,3-dithiolane (2) when the 2-substituent was a primary or secondary alkyl group. 2-Aryl derivatives of 1 were converted to ortho esters by the reaction with methanol in the presence of silver nitrate. 1,3-Dithian-2-ylium perchlorates and 2-alkylidene-1,3-dithianes were also prepared similarly from 1,3-propanedithiol.

C-H bond phosphorylation of ketene dithioacetals was achieved under transition-metal-free or AgNO3 mediated conditions. Synthetic transformations of the coupling product provided promising methods for the construction of highly functionalized p

A mild and efficient transthioacetalization of aldehyde acetals and oxathioacetals was carried out using 2,4,6-trichloro-1,3,5-triazine as a mild and inexpensive catalyst. Chemoselective transacetalization is impressive as aldehyde O,O- and O,S-acetals ar
Alkylidene[1,3]dithiolane-1,3-dioxides as potent Michael-type acceptors
Wedel, Tobias,Podlech, Joachim
, p. 2043 - 2046 (2008/02/05)
Nucleophilic additions of enolates, piperidine and methanol to easily prepared alkylidene[1,3]dithiolane-1,3-dioxides afforded the respective adducts with good yields. Selectivities were strongly dependant from the steric hindrance of the substrate and re
Fulvenes with Inverse Ring Polarization, 10. Electron Rich Heptafulvenes
Bauer, Walter,Betz, Ingrid,Daub, Joerg,Jakob, Lothar,Pickl, Wolfgang,Rapp, Knut M.
, p. 1154 - 1173 (2007/10/02)
The synthesis and structural properties of the electron rich heptafulvenes 3a - f are described.The compounds 3 have electron donor substituents at C-8.In the case of 3f NMR-spectroscopy revealed the presence of a boat conformation with bond alternation.H
