Description General description 4-Vinyl-1,3-dioxolan-2-one (VEC) is a cyclic carbonate, that can be synthesized from acrolein by reacting with sulfur ylide and CO2. The ruthenium-catalyzed transfer hydrogenation (TH) of VEC in the presence of 2-propanol forms 1,2-butanediol. Indolines and indoles undergo selective C-H allylation with VEC in the presence of rhodium(III) catalyst. Application 4-Vinyl-1,3-dioxolan-2-one may be used in the preparation of 2-arylbenzo[d]thiazole scaffolds. It may be used in the synthesis of the following multi-functional cyclic carbonates: • 4,4′-((hexane-1,6-diylbis(sulfanediyl))bis-(ethane-2,1-diyl))bis(1,3-dioxolan-2-one) (Bis-CC) • 2-ethyl-2-(((3-((2-(2-oxo-1,3-dioxolan-4-yl)-ethyl)thio)propanoyl)oxy) methyl)propane-1,3-diyl bis(3-((2-(2-oxo-1,3-dioxolan-4-yl)ethyl)thio)propanoate) (Tris-CC) • 2,2-bis(((3-((2-(2-oxo-1,3-dioxolan-4-yl)ethyl)-thio)propanoyl)oxy) methyl)propane-1,3-diyl bis(3-((2-(2-oxo-1,3-dioxolan-4-yl)ethyl)thio)propanoate) (Tetra-CC) Used to synthesize functional polymers.
