Abstract: This improved process for producing alkyl group-substd. aromatic hydrocarbons comprises reacting an aromatic hydrocarbon (1) with an alkylating agent (2) in the presence of a mordenite zeolite catalyst treated with a fluorine-contg. cpd. The alkylating agent (2) is selected from olefins, aliphatic lower alcohols, and alkyl halides (pref. propylene). The pref. aromatic hydrocarbon (1) is biphenyl, dibiphenyl or naphthalene. The typical product is p,p'-diisopropylbiphenyl. The fluorine-contg. cpds. can be hydrogen fluoride, ammonium fluoride, CF3Cl, SF6. As an example, 4,4'-dihydroxybiphenyl is produced by the acid-decomposition of 4,4'-diisopropyl biphenyldihydroperoxide which is obtd. by oxidising 4,4'-diisopropylbiphenyl with oxygen molecules. The above 4,4'-diisopropylbiphenyl is reacted with acylising agent to obtain 4,4'-diacyloxybiphenyl.

Abstract: The present invention relates to a process for the preparation, from e.g. anhydrovinblastine, of binary indole alkaloids effective as an anti-cancer drug, such as vinblastine, leurosidine, etc., wherein a trivalent iron source and hydride source are added in the presence of oxygen, thereby increasing a yield of an object compound. The yield of an object compound is improved still more by further addition, to the reaction system, of an oxalic acid ion source, malonic acid ion source, inorganic anion source, amino acid, etc.

Abstract: PURPOSE:To high selectively produce an aminophenol in a high yield by conducting an amination reaction of a divalent phenol in the presence of a mixture of phenol and another phenolic compound other than phenol. CONSTITUTION:In synthesizing an aminophenol of formula III by aminating a divalent phenol of formula I (R is H, a halogen or a lower alkyl) using a compound of formula II (R and R are H, a 1 to 10C alkyl, a 4 to 8C cycloalkyl), this reaction is conducted in the presence of a mixture of phenol and a phenolic compound other than phenol. As the phenol mixture, a mixture composed of phenol and one or more kinds of phenolic compounds selected from a group of cresols, chlorophenols, bromophenols and biphenols is used and a mixture of phenol and a biphenol is especially preferable. As the dihydric phenol of formula I, resorcin or hydroquinone is especially preferable. This aminophenol is useful as an intermediate for synthesis of agricultural and medical drugs and a raw material for pressure-sensitive or heat-sensitive dyes.
