| Application: | 4-Mercaptophenol (MPH) has been used to study the adsorption of MPH on silver coated polystyrene nanospheres by time-dependent surface-enhanced Raman scattering (SERS) spectroscopy. 4-Mercaptophenol may be used in the preparation of silylated monomer, which was employed for the synthesis of hyperbranched poly(ester-imide). 4-Mercaptophenol (H-4MP) reacts with metal tert-butoxides ([M(OBut)4]) to yield the following Group 4 phenoxy-thiols: • [(HOBut)(4MP)3M(μ-4MP)]2, where M = Ti, Zr, Hf • [(py)2M(4MP)], where M = Ti, Zr; py = pyridine • [(py)(4MP)3Hf(μ-4MP)]2 4-Mercaptophenol may be used in the synthesis of the following: • poly(ethersulfide)s via silylation followed by polycondensation with 2,6-dichloropyridine or 3,6-dichloropyridazine • 2,6-di-tertiarybutyl-4-mercaptophenol via Friedel-Craft’s alkylation with tert-butyl chloride in presence of a lewis acid |
