R 3 is optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted alkylcarbonyl, optionally substituted alkoxycarbonyl, aminocarbonyl, optionally substituted alkylaminocarbonyl, optionally substituted dialkylaminocarbonyl, —S(O) p (optionally substituted alkyl), —SF 5 , optionally substituted heterocyclyl, optionally substituted 6- to 10-membered aryl, optionally substituted 5- to 10-membered heteroaryl, a spirocyclic heterocyclyl-carbocyclyl group, a spirocyclic heterocyclyl-heterocyclyl group, a spirocyclic carbocyclyl-carbocyclyl group, a spirocyclic carbocyclyl-heterocyclyl group or —NR a R b , wherein R a and R b are independently H or optionally substituted alkyl; or R a and R b may form, with the nitrogen to which they are attached, a 3-, 4-, 5-, 6-, 7-, or 8-membered-heterocyclyl group, which may include one to three additional heteroatoms selected from the group consisting of N, O, Si and S and may be optionally substituted;
R 4 and R 4′ are independently in each occurrence, hydrogen, halogen, cyano, nitro, hydroxyl, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted cycloalkyl, optionally substituted cycloalkoxy, optionally substituted alkylcarbonyl, optionally substituted alkoxycarbonyl, optionally substituted aminocarbonyl, optionally substituted alkylaminocarbonyl, or optionally substituted di(alkyl)aminocarbonyl, optionally substituted alkylcarbonyloxy, optionally substituted alkylcarbonylamino, optionally substituted aryl, optionally substituted heteroaryl, —SF 5 , —SO p (optionally substituted alkyl or haloalkyl); or R 4 together with R 4′ together form a 2-6-membered chain optionally containing one or two heteroatoms selected from the group consisting of N, O, Si and S to form carbocyclic or heterocyclic ring together with the carbon atom to which they are attached; or —NR c R d , wherein R c and R d are independently H or optionally substituted alkyl; or R c and R d may form, with the nitrogen to which they are attached, a 3-, 4-, 5-, 6-, 7-, or 8-membered-heterocyclyl group, which may include one to three additional heteroatoms selected from the group consisting of N, O, Si and S and may be optionally substituted;
