The efficient conversion of H2S into mercaptan alcohols mediated in protic ionic liquids under mild conditions

The resource utilization of hydrogen sulfide (H2S) is an important and promising topic in energy chemical engineering. Previous products developed in our group through H2S conversion are sulfur or mercaptan acids. An alternative way to convert H2S is still desirable. Herein, we have developed a green and mild method to convert H2S into mercaptan alcohols by the addition reaction with epoxide mediated in tertiary amine-functionalized protic ionic liquids (PILs). Reaction kinetics, substrate scope, and regeneration experiments have all been explored. Almost quantitative conversion of substrates was realized with a catalytic loading of PILs at 30 °C. Water extraction was used to recycle the catalysts from the reaction system. It is believed that the excellent results, together with its operational simplicity and the ability to successively reuse the catalyst, make this new methodology environmentally benign and cost-effective. The generality of the H2S resource methodology gives it potential for application on an industrial scale.

A new strategy for chemoselective O-acylation of β-mercapto alcohols via alkylsilyl and stannyl protection

Chemoselective preparation of O-acylated derivatives from bis-protected mercapto alcohols was described. Trialkylsilyl and trialkylstannyl chloride are used to generate an intermediate with O- and S-protection. The intermediates from β-mercapto alcohols a

Regio- and enantioselective ring-opening of epoxides with HMDST: A straightforward access to 1,2-mercaptoalcohols

TBAF-catalyzed reaction of a range of substituted epoxides with hexamethyldisilathiane smoothly affords a direct and simple access to β-mercaptoalcohols in a highly regio- and stereo-selective way. Georg Thieme Verlag Stuttgart.

Synthesis of thiols via palladium catalyzed methanolysis of thioacetates with borohydride exchange resin

Various thiols are prepared quantitatively from the corresponding thioacetates via Pd catalyzed methanolysis with borohydride exchange resin under a mild and neutral conditions. One-pot synthesis of thiols from alkyl halides through the formation of alkyl thioacetates using thioacetate exchange resin followed by methanolysis is also described.

Synthesis and Insecticidal Activity of Oxazaphospholidines, Oxathiaphospholanes, and Thiazaphospholidines

Fifty-five new five-membered cyclic organophosphorus compounds including oazaphospholidines, thiazaphospholidines, and oxathiaphospholanes were synthesized, which have substituents at 4- or/and 5-positions besides at the 2-position.The thiazaphospholidines showed the highest insecticidal activity followed by oxathiaphospholanes and oxazaphospholidines.The position preference of substituents in insecticidal activity was most obvious in the oxazaphospholidines.It was preferable for insecticidal activity to have the substituent near the more basic atom: the 4-position for thiazaphospholidine and oxazaphospholidine, the 5-position for oxathiaphospholane, with the exception of 4- or 5-phenyl oxazaphospholidine.
