Abbr.phi^a= 2,4,6-(MeO)3C6H2- ; phi^a= 2,6-(MeO)2C6H3-.1. phi^aCOH reacted with a slight excess of acids to give carbenium salts [phi^a_3]X.Neutralization of 1 M acidic solution of [phi^a_3] resulted in the substitution of one of the para-methoxy groups. [phi^a_2]CHOH also reacted with perchioric acid to give [phi^a_2]CH_4, which was reduced in alcohols to give phi^a_2CH_<2->.2. phi^a_2CHOH reacted with acetone in the presence of catalytic amount of an acid to give phi^a_2CHCH_2COme. Me. Analogous reactions were observed with diethyl ketone, methyl phenyl ketone, propanal, and butanal. phi^a_2CHOH was reduced in alcohols or THF to give phi^a_2CH_2.3. Fc-CHphi^aOH [Fc= ferrocenyl group] reacted with a slight excess of an acid to give [Fc-CHphi^a]X(pKr+=3.0). The salt was reduced in 2-propanol to give Fc-CH_2phi^a and reacted with phi^b-CHphi^a_2,4. On treatment of p-HOcphi^b_2C_6H_4CAphi^bOH(Ar=phi^b, 4-MeOC_6, 4-MeOC_6H_4) with an acid, the Ar-group migrated onto the phenylene group.5. The reactivities of l, 8-dlrnethoxy-9-phenylxanthen-9-ol were compared with those of without difficulty.6. Novel method of preparation of triarymetals MAr_3(M=As, Sb, Bi) was developed. It is composed of the preparation of M(Sphi^b)_3 from metal oxides and phi^bSH and the reaction with LiAr. Both phiSH and M(Sphi^b)_3 are crystalline, and they can be handled without difficulty.7. Nucleophilic reaction rates of phi^b_2E increased in the order E= S <Se <Te, which were compared with those of phi^b_3 (M= P > As> Sb). The rates of phi^b_2EO increased in the order E= S <Se <Te).
