hydrazine, N-aminohydrazinecarboxamide, hydrazinecarboxylic acid hydrazide and 4­
aminosemicarbazide while thiocarbohydrazide includes TCH, l,3-Diamino-2­
thiourea, thiocarbazide, thiocarbonohydrazide, thiocarbonic dihydrazide,
carbonothioic dihydrazide and hydrazinecarbohydrazonothioic acid. The names
carbonohydrazide (preferred to carbohydrazide or carbazide) and
thiocarbonohydrazide are as per IUPAC rules [41]. The numbering scheme of
carbohydrazide and thiocarbohydrazide are given in Scheme l.l. The derivatives
formed by the removal of both hydrogens on N‘ or NS using aldehyde or ketone may
be named by adding the word ‘carbohydrazone or thiocarbohydrazone’ after the name
of the aldehyde or ketone.O Si
