A crystalline complex cpd. of formula (I) is new. R1-R2 = H, halogen, nitro, cyano, CF3, 1-15 C alkyl, 5-12 C cycloalkyl, 2-15 C alkenyl, 1-12 C haloalkyl, 1-12 C alkoxy, 1-12 C alkylthiol, unsubstd. or 1-4 C alkyl-substd. 6-10 C aryl(oxy), unsubstd. 7-12 C arylalkyl or 7-12 C arylalkyl substd. in the aryl gp. by 1-3 1-4 C alkyl gps., -CO2R6, -COR6 or -N(R)R8, where at least one of R1-R5 is H, halogen or 1-15 C alkyl, and each pair of substits. R1 and R2, R2 and R3, R3 and R4 or R4 and R5 together with the linking C atom, form a benzene or cyclohexenyl ring; R6 = 1-20 C alkyl, 2-20 C alkyl interrupted by O, S or N-R9, unsubstd. 7-12 C arylalkyl or 7-12 C arylalkyl substd. in the aryl gp. by 1-3 1-4 C alkyl gps.; R7, R8 = H, 1-24 C alkyl or 2-24 C alkyl interrupted by O, S or N-R9; R9 = H or 1-8 C alkyl; R10 = 1-15 C alkyl, 2-20 C alkyl interrupted by O, S or N-R9, 5-12 C cycloalkyl, 2-15 C alkenyl, 1-12 C alkoxy, 1-12 C (alkylthio, unsubstd. or 1-4 C-alkyl-substd. 6-10 C aryl(oxy), unsubstd. 7-12 C arylalkyl or 7-12 C arylalkyl substd. in the aryl gp. by 1-3 1-4 C alkyl gps.; and m = integer of 2-5. Also claimed are: (1) a coating compsn. comprising an organic film-forming binder and as corrosion inhibitor cpd(s). of formula (I); (2) a method of protecting a corrodible metal substrate comprising applying the above coating compsn. and then drying or curing the coating; and (3) prepn. of (I) comprising reacting a keto-acid of formula (II) with a morpholine deriv. of formula (III) without a solvent or in the presence of an aprotic solvent. R1-R5, R10, m = as before. |
