(d) CONR2R3 wherein R2 and R3 independently represent C1-6alkyl and hydrogen;
(e) loweralkenyl;
(f) -COR2
(g) -CH2OR2;
(h) loweralkynyl;
(i) -CH2-NR2R3;
(j) -CH2SR2;
(k) =0; or
(I) -OR2;
Ar and Ar' are the same or different from each other and are (a) phenyl or substituted phenyl of formula
where R4-R8 independently represent H, RO-, R2S-, R2SO2-,CF3O-, CF3S-, R2R3N-, -OCH2CO2R2, -SO2NR2R3, -C02R2, -NR2SO2R3, COR2, N02, or CN or R4-R5, R5-R6, R6-R7 and R7-R8 are joined together forming a bridge;
