Effect of polarity and steric on the rate addition of free radicals to Alkenes [PDF]
Kirkuk Journal of Science, 2009 In this investigation, the effective factors on the addition rate for hydroxy methyl and cynomethyl free radicals to some alkenes have been studied using quantum mechanics methods. Where in this study, physical properties like the electron density on the

Alkene-oxo and alkene-alkene coupling on Pt(II) [PDF]
, 2021 Tetranuclear Pt(II) oxo-complex [(COD)4Pt4([mu]3-O)2Cl2](BF4)2 (1) (COD = 1,5- cyclooctadiene) was found to readily react with a variety of alkenes (ethylene, norbornene, propylene and cyclopentene). The most significant discovery resulted from the norbornene reaction, which gave platinaoxetane [(COD)2Pt2(OC7H10)Cl]BF4 (4), the first metallaoxetane ...
