Experimental and modeling study of the autoignition of 1-hexene/iso-octane mixtures at low temperatures [PDF]
, 2005 Autoignition delay times have been measured in a rapid compression machine at Lille at temperatures after compression from 630 to 840 K, pressures from 8 to 14 bar, \Phi = 1 and for a iso octane/1 hexene mixture containing 82% iso-octane and 18% 1 hexene.

Remote functionalization by tandem radical chain reactions [PDF]
, 1997 Normal radical relay chlorination of cholestan-3α-ol directed by an attached m-iodobenzoate ester group affords a 9α-chloro steroid, but when the same reaction is conducted in the presence of an excess of CBr4 the product is a 9α-bromo steroid ...

Selective deuteration as a tool for resolving autoxidation mechanisms in α-pinene ozonolysis [PDF]
Atmospheric Chemistry and Physics, 2023 Highly oxygenated organic molecules (HOMs) from α-pinene ozonolysis have been shown to be significant contributors to secondary organic aerosol (SOA), yet our mechanistic understanding of how the peroxy-radical-driven autoxidation leads to their ...

Synthesis of a terminal Ce(iv) oxo complex by photolysis of a Ce(iii) nitrate complex. [PDF]
, 2017 Reaction of [Ce(NR2)3] (R = SiMe3) with LiNO3 in THF, in the presence of 2,2,2-cryptand, results in the formation of the Ce(iii) "ate" complex, [Li(2,2,2-cryptand)][Ce(κ2-O2NO)(NR2)3] (1) in 38% yield. Photolysis of 1 at 380 nm affords [Li(2,2,2-cryptand)
