1,3-Benzothia-zole-oxalic acid (2/1)
Abstract:
The asymmetric unit of the title compound, C(7)H(5)NS·0.5C(2)H(2)O(4), contains one benzothia-zole mol-ecule and half an oxalic acid mol-ecule, the complete mol-ecule being generated by inversion symmetry. The benzothia-zole mol-ecule is essentially planar, with a maximum deviation of 0.007 (1) Å. In the crystal, the benzothia-zole mol-ecules inter-act with the oxalic acid mol-ecules via O-H⋯N and C-H⋯O hydrogen bonds generating R(2) (2)(8) (× 2) and R(4) (4)(10) motifs, thereby forming supra-molecular ribbons along [101].

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
