용도

Thiophenol acts as a reagent to synthesize alfa, beta-unsaturated sulfides, beta-lactones and (3H-benzo[c][1,2]diselenol-3-yl)(phenyl)sulfane. It is used as an antinematodal agent and an intermediate in the preparation of sodium thiophenolate, pentachlorothiophenol and alkyl phenylsulfides. It acts as an inhibitor of human fibroblast collagenase in vitro.

참고

Incompatible with strong acids, bases and oxidizing agents.

For a detailed investigation of alkylation using, e.g. K2CO3 in acetone, see: Synth. Commun., 22, 1691 (1992). Unactivated aryl chlorides undergo nucleophilic substitution in the presence of K2CO3 in NMP to give aryl sulfides: J. Org. Chem., 56, 862 (1991).

Michael additions occur readily with electron deficient alkenes. Subsequent chlorination with NCS and dehydrochlorination provides a stereoselective route to vinyl thioethers: J. Org. Chem., 46, 235 (1981):

The Cu(I) derivative, phenylthiocopper forms complexes with alkyllithiums, which are useful alkyl transfer reagents, undergoing conjugate addition to enones, coupling with alkyl iodides to alkanes, and converting acid halides to ketones: J.

Chlorination of PhSH with NCS: J. Org. Chem., 37, 1367 (1972), or SO2Cl2: Org. Synth. Coll., 8, 550 (1993), gives the useful reagent benzenesulfenyl chloride, PhSCl.

Dilithiation of PhSH with n-BuLi and TMEDA gives exclusive ortho-metallation: J. Am. Chem. Soc., 111, 654, 665, 2327 (1989). Subsequent treatment of the dilithio species with DMF, followed by in situ reaction with chloroacetone provides a useful route to the benzo[b]thiophene system: J. Org. Chem., 58, 1293 (1993):

Interception of the DMF adduct provides a source of the unstable 2-mercaptobenzaldehyde. Alternatively, ortho-metallated thiophenols can be formed by lithiation of the THP ether, in which coordination by oxygen favors ortho-lithiation: J. Am. Chem. Soc., 111, 658 (1989).
