Tetrasulfur tetranitride and tellurium tetrachloride react in dichloromethane to form a 1:1 adduct TeCl4·S4N4 (1). The crystal structure of 1 shows that TeCl4 is bonded to the S4N4 ring through a Te–N linkage. As a consequence, the transannular S···S bonds in S4N4 are broken ...
(TeBr3)(Zr2Br9) can also be obtained by the reaction of two equivalents of ZrBr4 with TeBr4 at 260°C. The crystal structure is built of Zr2Br9 ions, that form face-sharing double octahedra, and of pyramidal TeBr3 ions. Each TeBr3 ion exhibits three Te - Br contacts to two ...
Moreover, the TEB/DTMeAB pair exhibited excellent selectivity in the nucleophilic attack process, where the propagating species selectively attacked the less sterically hindered methylene carbon of PO. As a result, greater than 99% of PPMTC linkages were tail-to-head (T-H) structure (Figures ...
