2-Acetyl, 2-cyano-, and 2-nitro-2-phenylazopropionic acid derivatives suffer cleavage of the phenylazo-grouping on treatment with borontrifluoride, giving benzenediazonium tetrafluoroborate and the corresponding difluoroboron propionic acid derivative; 2-cyano- or 2-nitro-2-phenylazoisobutyronitrile and the corresponding amides behave similarly, but 1-phenylazo-2-naphthol gives a difluoroboron salt, and
The present invention relates to new cephalosporin compounds of the formula(I), pharmaceutically acceptable non-toxic salts thereof, and physiologically hydrolyzable esters and solvates thereof, which have potent and broad antibacterial activities ##STR1## wherein R.sup.1 is a C.sub.1.about.4 alkyl, C.sub.3.about.4 alkenyl, C.sub.3.about.4 alkynyl group, or --C(R.sup.a)(R.sup.b)CO.sub.2 H.sub.1 wherein R.sup.a and R.sup.b are the same or different, and each is a hydrogen atom or a C.sub.1.about.4 alkyl group, or R.sup.a and R.sup.b form a C.sub.3.about.7 cycloalkyl group with the carbon atom to which they are linked; R.sup.2 is a C.sub.1.about.4 alkyl, C.sub.3.about.4 alkenyl or C.sub.3.about.4 cycloalkyl group, a substituted or unsubstituted amino group, or a substituted or unsubstituted phenyl group; R.sup.3 is hydrogen or a C.sub.1.about.4 alkyl group; and Q is N or CH. The invention further relates to a process for preparing said compounds, and to pharamaceutical compositions containing said compounds.

4-naphthoquinone-4-imine (3) and 5-amino-4-methylisoxazole (4), were isolated. The pathway for degradation of 1 in acidic and neutral pH followed consecutive first-order kinetics since 2 undergoes hydrolysis giving 2-hydroxy-1,4-napthoquinone (6) and 2-methylcyanoacetamide (5). No appreciable buffer effect on the degradation of 1 and 2 was observed for any of the buffer species in this study. The pH-rate

2-Substituted 3-amino-3-(methylthio)acrylonitriles cyanoketene S,N-acetals are synthesized by two convenient methods. The imino esters of their hydrochloride salts are found to be good starting materials for the synthesis of 4-substituted 3,5-diaminopyrazoles and 2,5-disubstituted 1,3,4-oxadiazoles.
