Determination of Alkyl Thioureas, Isothiocyanates and Amines with Iodine Monochloride

Tandem regioselective synthesis of tetrazoles and related heterocycles using iodine.

A one-pot, tandem process has been developed for the synthesis of a library of tetrazoles from aryl isothiocyanates. Condensation of aryl isothiocyanates with ammonia, and aryl amines (R-NH(2)) provided mono, 1,3-disubstituted symmetrical and unsymmetrical thioureas, which on desulfurization with molecular iodine (I(2)) led to formation of the corresponding heterocumulene (cyanamides or carbodi...

Iodination of nucleic acids in organic solvents with iodine monochloride.

Iodine monochloride, labeled with 1z51, iodinated ribonucleic acid and deoxyribonucleic acid dissolved as hexadecyltrimethylammonium salts in anhydrous dimethylformamide or N-ethyl acetamide. In the case of RNA (polyuridylate, polycytidylate, and soluble RNA) 5-iodouridine S/-phosphate, 8-iodoguanosine 5’-phosphate, and 5-iodocytidine 5’-phosphate are found. After 24 hours of reaction, 32% of U...

HPLC analysis of alkyl thioureas in an orthopaedic brace and patch testing with pure ethylbutylthiourea

Some quantitative aspects of the labelling of proteins with 125 I by the iodine monochloride method.

The labelling of proteins by the iodine monochloride method was studied by using a mathematical model. The equations used were primarily derived from the mass law equation of the isotopic exchange reaction between [(125)I]iodide and iodine monochloride. For convenient application, all equations were programmed into a computing desk-top calculator. To support the validity of the theoretical mode...
