[4+2] Cycloaddition of C60 to 2-(thi)oxo-4,5-bis(methylene)-1,3-dithioles: en route to the bis-linking of tetrathiafulvalene to C60
摘要:
The title reaction carried out from S-propargyl xanthate 3 or 2-(thi)oxo-4,5-bis(bromomethyl)-1,3-dithioles 4a and 4b with C-60 is presented and some conversions of the synthesized cycloadducts 2a and 2b in several 1,3-dithiole derivatives are described.
