The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II)( cas:14481-08-4 ) is researched.SDS of cas: 14481-08-4.Rahman, M. B. Abdul; Evans, J.; Dent, A. J. published the article 《Time-resolved energy dispersive extended X-ray absorption of fine structure (EXAFS) measurement of oligomerisation reaction catalysed by nickel homogeneous catalyst and alkyl-aluminium co-catalyst》 about this compound( cas:14481-08-4 ) in Materials Science Research India. Keywords: nickel diketonate alane catalysis oligomerization hexene energy dispersive EXAFS; ab initio phase shift energy dispersive EXAFS hexene oligomerization. Let’s learn more about this compound (cas:14481-08-4).
Energy Dispersive EXAFS (EDE) data was analyzed for bis(dipivaloylmethanato)nickel:AlEt2(OEt):1-hexene, using curved wave theory with ab initio phase shifts. The derived parameters for the proposed intermediate [(tert-BuC(O)CHC(O)tert-Bu)NiEt(η2-1-hexene)] were in good agreement, within exptl. error = 0.02-0.05 Å for the bond distances. A stopped flow system was used for in situ time-resolved EDE studies on the Ni systems at room temperature The growth of a pre-edge feature and change at the top of the edge can be clearly seen to show the reaction reached completion in <6 s indicates averaged distances of 3 Ni-O/C 2.00 Å. Compounds in my other articles are similar to this one(Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II))SDS of cas: 14481-08-4, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
