Name: Pentaerythrityltetrabromide. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Pentaerythrityltetrabromide, is researched, Molecular C5H8Br4, CAS is 3229-00-3, about A dynamic NMR study of sulphur inversion in transition metal complexes of 2,6-dithiaspiro[3.3]heptane (2,6-DTSH), 2,6-DTSH-2-oxide and 2,6-DTSH-2,2-dioxide. Author is Abel, Edward W.; Orrell, Keith G.; Poole, Mark C.; Sik, Vladimir.
The following complexes were synthesized [W(CO)5L1], [{W(CO)5}2L1], [W(CO)5L2], [W(CO)5L3], [{PdCl2(PPh3)}2L1], [PdCl2(PPh3)L2] and [PdCl2(PPh3)L3] where L1 = 2,6-dithiaspiro[3.3]heptane (2,6-DTSH), L2 = 2,6-DTSH-2-oxide and L3 = 2,6-DTSH-2,2′-dioxide. In solution these complexes exhibit pyramidal inversion of the metal-coordinated sulfur atom(s), rates and activation energies of which were evaluated by total NMR bandshape anal. ΔG⧧ values were in the range 45-50 kJ mol-1. These magnitudes are discussed in terms of ring geometry distortions and sulfur lone pair interactions.
After consulting a lot of data, we found that this compound(3229-00-3)Name: Pentaerythrityltetrabromide can be used in many types of reactions. And in most cases, this compound has more advantages.
