Thiadizines

Novel heterocyclic compounds of the formula: STR1 wherein either X is --CR1 R2 -- and Y is oxygen, sulphur or --NR3, wherein R1, R2 and R3, which may be the same or different, each is hydrogen or alkyl of up to 4 carbon atoms; or X is oxygen, sulphur or --NH-- and Y is --CH2 --; wherein R4 and R5, which may be the same or different, each is hydrogen, cyano, nitro, amino or hydroxy, or alkylthio of up to 4 carbon atoms, or has various other meanings defined in claim 1, provided that R4 and R5 are not both hydrogen; or wherein R4 and R5 are joined together such that with the benzene ring A they form a benzheterocyclic ring as defined in claim 1; and therein the benzene ring A may optionally bear one or more further substituents; or a salt thereof where appropriate. These compounds possess cardiotonic properties, and some of them possess peripheral vasodilator properties, and they are useful for the treatment of acute or chronic heart failure. Representative of the compounds is N,N-dimethyl-p-(5,6-dihydro-5-oxo-4H-1,3,4-thiadiazin-2-yl)benzamide. Also disclosed are processes for the manufacture of the compounds and pharmaceutical compositions containing them.

Infrared spectra of several thiopiperidides and thiomorpholides

Infrared spectra in the 1700-500 cm-1 region have been studied for several types of thiopiperidides (thiobenzoylpiperidides, thiocinnamoylpiperidides and phenylthioacetpiperidides) and for the corresponding thiomorpholides.Three characteristic thioamide bands were located and assigned.The behaviour of these bands on molecular complexing (with iodine as an electron acceptor) was used to support the assignments.The experimental data were discussed in terms of the theoretical results obtained by an HMO procedure.

Dyeing keratinous fibers

A process for dyeing keratinous fibers such as hair which comprises reacting the hair with a dyestuff of the general formula EQU1 where X is a chromophoric group, such as a group formed by coupling a phenylene diazonium salt with a diazo coupling compound
