The invention provides a compound of Formula I ~ 't 5a wherein each of R1, R1, and Rs, is a group independently selected from hydrogen, CI-C2oalkyl, C 10 C2oalkonyI, aryl, alkaryl. aralkyl, heterocyclyl, hydny, halogen, amino, alkylamino, dialkylamino, alkyloxy, nitro, carboxyl, aminocarbonyl, alkyloxycarbonyl, alkynyl, alkylcarbonyloxy and alkylcarbonylmino, wherein each alkyl, alkenyl, alkyloxy, ary], akaryl, aralkyl, or heterocyclyl group present in these may be substituted with one or more groups selected from hydroxy halogen, alkyloxy, amino, alkylamino, dialkylamino, alkyloxy. nitro, carboxyl, aminocarbonyL 15 'alkyloxycarbonyl, alkynyl, alkylcarbonyloxy and alkyloarbonylamino; each of R2, R4 and R6 is a group selected from hydrogen and Ct-Czoalkyl; each ofZi, Z and 4 as a group chosen from -C(Ry7Ps)-, -C(R7R)-C(Rjo)-, -C(k7R,)-C(R.Ri)-C(Ri P-L+, -C(RRa)-C(RRi)-C(Riilty)-C itRzvC(RisRi,, and -C(R 7R-C(RRio)-C(Ru1 R4)-C(RR 1 4)-(CH2 ).-C(R5 Rs)-; each of R,. R, Rtn. Ra and Ras is a group independently selected from hydrogen, C1 Czoalkyl, CI-2oalkenyl, aryl, alkuryl, aralkyl, heterocyclyl, hydroxy, halogen, amino, alkylamino, 5 dialkylamino, alkyloxy, nitro, carboxyl, aminncarbonyl, alkyloxycarbony4, alkynyl, alkylcarbonyloxy or alkylcarbonylamino, wherein each alkyl, alkenyl, alkyloxy, aryl, alkaryl, eralkyl, or heterocyclyl group present in these may be substituted with one or more groups selected from hydroxy, halogen, amino, alkylamino, dialkylamino, alkyloxy, nitro, carboxyl, aminocarbonyl, alkyloxycarbonyl, ulkynyl, alkylcarbonyloxy and aky4carbonyumino; and each of R2 , R4. R &, i, Rio. Ru, R 14 and 10 R 16 is chosen from hydrogen and Ci-Cmalkyl and wherein not only are ZI, Z2, and Z3 the same or different but also Rp, Rg and when present R, RIo, RI], R12, R, R14, Ris, Ri& may be the same in said Zi, Z2, and Z3 or in two of those groups, or those R groups maybe different in all three Z groups; 15 Z, Z2 and Za with more than one carbon atom maybe included in the molecules such that the C atom bearing R7 is linked to that bearing R1. R3 and Rs respectively or so that it is linked to the nitrogen atom; and Ri. R2, R3, R4, Rs, R4, ZI, Z2, and Z3 are selected so that when the three rings each contain 5 to 8 membes (including the boron and nitrogen atoms), at least one ring bears a, group other than 20 hydrogen, methyl, methoxy or ethoxy. These compounds are useful in preservative compositions, especially those used in preserving wood. |
