A novel class of compounds which are useful as plant growth regulators is disclosed, having the general structural formula:
In which R is C, to C4 alkyl, alkenyl or alkynyl to which may be attached phenyl, pyridyl, benzoyl, phenoxy, halophenoxy, halobenzoyl, N-phenylcarbamyl, N-alkylcarbamyl, N-trifluoromethylthiadiazolylcarbamyl, carboxy, carbalkoxy or halo substituents,
R1 is H, C, to C3 alkyl, alkenyl or alkynyl to which may be attached phenyl, halophenyl or phenoxy groups, acetyl, or R and R1 together may be C2 to C4 alkylene,
Ar is phenyl or benozyl,
R2 is C, to C4 alkyl, alkoxy, alkylene, alkylamino or alkylthio, phenoxy, benzyloxy, carbalkoxy, acetyl, methylenedioxy, trifluoromethyl, nitro, halo or cyano and n may be zero or an integer from 1 to 4, with the provision that at least one position ortho to the point of attachment of a phenyl ring of the Ar structure must be unsubstituted,
R3 is lower alkyl or halo and n' may be zero or an integer from 1 to 4.
