2,6-Dimethoxyphenyl Derivatives of a Variety of Elements

缩写phi^a=2，4，6-(MeO)3C6H2-；Phi^a=2，6-(MeO)2C6H3-1。Phi^ACoH与少量过量的酸反应生成了卡宾盐[Phi^a3]X。[Phi^a3]的1M酸性溶液中和后，一个对甲氧基被取代。[Phi^a_2]CHOH还与高氯酸反应生成[Phi^a_2]CH_4，后者在醇中还原得到Phi^a_2CH_&lt；2-&gt；Phi^a_2CHOH与丙酮在催化量的酸存在下反应生成Phi^a_2CHCH_2Comm。我。二乙酮、甲基苯基酮、丙醛和丁醛也发生了类似的反应。Phi^a_2CHOH在醇或四氢呋喃中还原得到Phi^a_2CH_2.3。FC-CHphi^AOH[FC=二茂铁基]与少量过量的酸反应得到[FC-CHphi^a]X(pKr+=3.0)。该盐在异丙醇中还原得到FC-CH2phi^a，并与phi^b-CHphi^a 2，4反应。在p-Hocphi^b_2C_6H_4CAphi^Boh(Ar=Phi^b，4-MEOC_6，4-MEOC_6H_4)与酸反应时，Ar-基团迁移到亚苯基上。比较了L、8-二甲氧基-9-苯基黄烷-9-醇与无困难化合物的反应活性。提出了制备三元金属MAR_3(M=As，Sb，Bi)的新方法。它由金属氧化物与Phi、BSH反应制备M(phi^b)_3及与LiAr的反应组成。Phish和M(phi^b)_3都是结晶性的，可以很容易地处理。与Phi^b_3(M=P&gt；As&gt；Sb)相比，Phi^b_2e的亲核反应速率按E=S&lt；Se&lt；Te的顺序增大。Phi^b_2EO的速率按E=S&lt；Se&lt；Te的顺序递增。

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).
