Similarly, chlorobenzopyrano[2,3-c]pyrazole 376 on treatment with benzoic acid hydrazide gives benzopyranodia-zolotriazole derivative 462 (Equation 105) <2000FES641>. 

With phenyllithium, the iminophosphoranes of benzoic acid hydrazides 157 can be deprotonated, as shown in Scheme 62.0-Acylation of the amide-enolates 158 affords intermediates 159, which are in turn cyclized by an aza-Wittig reaction to 1,3,4-oxadiazoles 160 (68JA5626). 

Triazolopyridines and 1,2,4-triazolopyrimidines were synthesized using a modified Mitsunobu reaction starting from acylated 2-hydrazinopyridines and acylated-hydrazinopyrimidines under mild conditions <07ARK132>. A series of 3-alkylthio-4,5-diaryl-4//-1,2,4-triazoles were prepared from benzoic acid hydrazides <07JHC1323>.

Li et al. [30] gave the solvent free synthesis of 2-aryl-5-(coumarin-3 -yl)-l,3,4-oxadiazoles (xxv) in high yields by reacting the coumarin-3-carboxylic acid (xxiii) with (un)substituted benzoic acid hydrazides (xxiv) in presence of PEG supported dichlorophosphate under microwave irradiation. 

The reaction of benzoic acid hydrazide with carbon disulfide in basic medium was first described by Busch and Starke (63) who identified the reaction product as benzoyldithiocarbazic acid (LXXXII). Hog-garth (767) found, that, in the absence of alkali, 5-phenyl-Z]4-l,3.4-oxadiazoline-2-thione (LXXXIII) and 1,2-dibenzoylhydrazine were formed in the reaction of benzoic acid hydrazide with carbon disulfide. If this same reaction is carried out in pyridine, there is formed, beside 5 -phenyl-J 4-1,3,4-oxadiazoline-2-thione (LXXXI11), 3 -phenyl-4-ben z-amido-J2"I>2,4-triazoline-5-thione (LXXXV), probably from the intermediately formed t,5-dibenzoylthiocarbohdrazide (LXXXIV). 

Ainsworth (2) has questionned this interpretation. He finds that the reaction mixture of benzoic acid hydrazide and carbon disulfide does not show the characteristic absorption bands of the xanthate function (between 8.5 and 10 y) at any time during the course of the reaction.

Get an aliquot SOpg.mL-i of the reducing sugar sample, add 5mL p-hydroxy benzoic acid hydrazide reagent (mixed in the same day) shake in vortex, incubate in water bath at 100°C by six minutes, cool until room temperature, and read the absorbance in spectrophotometer at 410nm... 

In the reaction of substituted chloroformamidine hydrochlorides with phenylhydrazine or with benzoic acid hydrazide the corresponding guanidines are obtained. Thus, from tetramethylchloroformamidinium chloride (LX) and phenylhydrazine, a guanidine LXI is obtained in good yield ( ). 

The rates of Tl(lll)-oxidation of benzoic, p-chlorobenzoic acid, and p-methoxy benzoic acid hydrazides in acidic medium increased with [H+] and decreased with [Cl ]. The participation of a Tl(lll)-substrate complex had been proposed. ...
