Hydrosilylation of diallyl sulfide with trichlorosilane

Conclusions By the hydrosilylation of diallyl sulfide with trichlorosilane, catalyzed by the Nt(acac)₂-tert-phosphine systems, mono- and bis-trichlorosilyl derivatives were obtained. Conditions were found for the preferential preparation of each of these compounds. Besides mono- and bis-adducts, 1-trichlorosilyl-4-thioheptane is also formed.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2119–2121, September, 1981.     

Boiling-up of liquid argon at high superheatings under the impact of weak ultrasonic fields

The technique of lifetime measurement for metastable liquid and continuous depressurization technique were applied for study of kinetics of spontaneous cavitation in superheated liquid argon under impact of weak ultrasonic fields. It was demonstrated that acoustic cavitation may occur through the mechanism of homogeneous generation of vapor phase or through “swinging” of vapor bubbles generated by high-energy particles and/or other kinds of initiative factors. The thresholds of acoustic cavitation are described by the theory of homogeneous nucleation.
