Bisthiourea: Thermal and structural investigation

Bisthiourea derivatives 1,1′-(ethane-1,2-diyl)bis(3-phenylthiourea), 1,1′-(propane-1,3-diyl)bis(3-phenylthiourea), and 1,1′-(butane-1,4- diyl)bis(3-phenylthiourea) have been synthesized and characterized by IR, 1H NMR, and 13C NMR. Suitable crystals of 1,1′-(propane-1,3-diyl)bis(3-phenylthiourea) were grown for single-crystal X-ray analysis and from the data it was observed that they organize into the P-1 space group. The thermal decomposition of these compounds has been studied by TG-DSC.

TRANSFORMATIONS OF PYRIDINIUMS DERIVED FROM AMINO-ALCOHOLS AND FROM DIAMINES

Pyridiniums derived from amino alcohols cyclise to ethers or rearrange to aldehydes on heating.Monopyridiniums from diamines can be acylated or converted into ureas or thioureas: these products cyclise on heating in solution to give dihydro-thiazoles, -4H-thiazines, -oxazoles, -4H-oxazines, or tetrahydro-3H-thiazepines.
