In 1951,Bucka and Todd
[1]
found that 3-(
p
-chlorophenyl)-1,1-dimethylurea (CMU) is an outstanding weed killer. It is highly toxic to many plants and possesses long-lasting herbicidal effect in the soil. In 1953,Sharp
et al
[2]
found that 1,1-dimethyl-3-phenylurea is effective in eradicating deep-rooted perennial weeds in croplands. However,it persists in soil as a sterilant for a shorter period than 3-(
p
-chlorophenyl)-1,1-dimethylurea. Since the structure of 3-(
p
-chloro-phenyl)-1,1-dimethylurea is similar to that of CMU, the senior author synthesized and tested it in Nalco
*
in 1953 as a herbicide. It was found to be as effective to plants as 3-(p-chlorophenyI)-1,1-dimethylurea. However,it took a longer period for the herbicidal effect.

Starting with
p
-trimethylsilyltoluene,the methyl group was brominated with
N
-bromosuc-cinimide into bromomethyl group and thence
p
-trimethylsilylbenzyl-substituted acetoacetic ester,malonic ester and nitrile were prepared. The bromomethyl get up was successfully converted into aldehyde group by means of Sommlet reaction.After the methyl group in p-trimethylsilyltoluene was oxidized into carboxyl group,the amide was prepared through the action of thionyl chloride and ammonia. Similarly, some esters and amides of p-triphenylsilylbenzoic acid,dimethyldi(
p
-carboxylphenyl) and diphenyldi(
p
-carboxyl) silane were synthesized. No cleavage of the carbon-silicon bond was found during the thionyl chloride treatment.

Numerous well-known drugs acting on various nerve systems are phenyl,benzyl or benzhydryl esters,ketones or ethers carrying a β-amino substituted carbon chain. Procaine, Trasentine,Amidone and Benadryl are examples of such types. It appears interesting to see if the corresponding sulphones would also be pharmacologically active. β-Aminosulphones are the oxidation products of the corresponding sulphides. Moreover,the β-aminosulphides could be regarded as the ring-cleaved derivatives of phenothiazine (Ⅰ),and the latter compound is the nucleus of a number of medicinal agents such as promethazine and chlorpromazine. A number of β-aminosulphides and β-aminosulphones are therefore prepared in the present work for pharmacological examinations.

Organo-antimonyl derivatives are effective schistosomicides. Their mechanism may be d ae to the interaction between antimony and mercapto-containing enzymes in the parasites. Since it seems that Mannich bases, which are active alkylating agents, are also capable to fix the mercapto compounds, it would be interesting to see if certain Mannich bases were active against schistosomiasis. A number of Mannich bases have therefore been prepared from substituted phenols in the present woik.
