摘要

The invention comprises compounds of the formula FORM:1061120/C2/1 wherein R and R1 are hydrogen, halogen, 1-pyrazolyl, alkyl, aryl, alkoxy, aryloxy, alkylamino, arylamino, azido, alkylmercapto or arylmercapto or conjointly are FORM:1061120/C2/2 where Z is a saturated heteroatom which may be O, S, N or P, and Cl1 is a hydrocarbon polyradical which may be a pair of diradical linking units or a tetraradical linking unit thus giving a polymeric repeat unit of the formula FORM:1061120/C2/3 where X is N or CR4; R2, R3 and R4 are hydrogen, alkyl, halogen, aryl, cyano, alkoxy, alkoxycarbonyl, arylamino, nitro, acyl, mercapto or hydroxy, or R2 and R4 are conjointly benzo or naphtho, X1 is X or C(Cl11)n giving a polymeric repeat unit of the formula FORM:1061120/C2/4 where Cl11 is an a ,o -hydrocarbylene of 1-18 carbon atoms and n is 0 or 1. The compounds are prepared by reacting ClBRR1R11 or BRR1R11, where R11 is as R and R1 and Cl is an electron pair donor, with an azole of the formula FORM:1061120/C2/5 where X is N or CR4 and R4 is as defined above or is FORM:1061120/C2/6 the reaction being carried out at a temperature of at least 25 DEG C. The product may then be reacted with a compound of the formula FORM:1061120/C2/7 The preparation of various intermediates is described; thus 4-butyl-3,5-dimethyl pyrazole is prepared in Example 21, 3,5 bis(trifluoromethyl)-3,5 dihydroxypyrazolidine and 3,5-bis(trifluoromethyl) pyrazole in Example 22, 4-perfluoroisopropylpyrazole in Example 24 and 4,41-methylenedipyrazole in Example 26.ALSO:The invention comprises polymers containing repeating units of the formula FORM:1061120/C3/1 FORM:1061120/C3/2 where Z is a saturated heteroatom which may be O, S, N or P; Q1 is a hydrocarbon polyradical which may be a pair of diradical linking units or a tetraradical linking unit; X is N or CR4; R2, R3 and R4 are hydrogen, alkyl, halogen, cyano, aryl, alkoxy, alkoxycarbonyl, arylamino, nitro, acyl, mercapto or hydroxy, or R2 and R4 conjointly are benzo or naphtho; R and R1 are hydrogen, halogen, 1-pyrazolyl, alkyl, aryl, alkoxy, aryloxy, alkylamino, arylamino, azide, alkylmercapto or arylmercapto; Q11 is an a ,o -hydrocarbylene of 1-18 carbon atoms and n is 0 or 1. The compounds are prepared by reacting QBRR1R11 or BRR1R11, where R11 is as R and R1 and Q is an electron pair donor with an azole of the formula FORM:1061120/C3/3 where X is N or CR4 and R4 is as defined above or is FORM:1061120/C3/4 and the product is, if desired, reacted with a compound of the formula FORM:1061120/C3/5
