AB INITIO CALCULATION OF CAGE-LIKE SILOXANES AND METALLOSILOXANE STRUCTURE FORMATION

Тонкие химические технологии, 2013
Several ab initio (DFT-B3PW91/6-31g(d,p)) calculations of cage-like siloxanes (MeSiO1.5)n (n = 4-12) have been made. It was shown that cubane-like structure (MeSiO1.5)8 is the most stable one.

Single‐Step Generation of β‐Ketosulfides from Epoxides and Thiols Catalyzed by a Ru(II)–Pincer Complex

European Journal of Organic Chemistry, EarlyView.
β‐Ketosulfides can be generated in a single step through direct coupling of epoxides and thiols, catalyzed by a Ru(II)–pincer complex. This process requires no substrate preactivation with leaving groups or the use of additives, and liberates H2 gas as a byproduct.
