Odorless substitutes for foul-smelling thiols: syntheses and applications
摘要:
Several alkanethiols and p-alkylphenylmethanethiols were synthesized, and their odors were compared with those of ethanethiol and benzyl mercaptan by human and instrumental sensors. Among the various thiols analyzed. 1-dodecanethiol (1) and p-heptylphenylmethanethiol (3) were revealed to be odorless. 1-Dodecanethiol (1) has been used instead of ethanethiol for dealkylation of ethers, and p-heptylphenylmethanethiol (3) can replace benzyl mercaptan in the preparation of a 1,3-mercapto alcohol from an alpha,beta -unsaturated ketone. These odorless thiols will greatly improve the physical environment of the researcher working with these foul-smelling compounds. (C) 2001 Elsevier Science Ltd. All rights reserved.
Development of new odorless thiols (dodecanethiol, 4- n -heptylphenylmethanethiol, 4-trimethylsilylphenylmethanethiol, 4-trimethylsilylbenzenethiol) and an odorlesssulfide (1-methylsulfanyldodecane) and their applications to dealkylation, Michael addition, Swern oxidation, and Corey - Kim oxidation are described.
