The arene–alkene photocycloaddition [PDF]
Beilstein Journal of Organic Chemistry, 2011 In the presence of an alkene, three different modes of photocycloaddition with benzene derivatives can occur; the [2 + 2] or ortho, the [3 + 2] or meta, and the [4 + 2] or para photocycloaddition. This short review aims to demonstrate the synthetic power

Tethered Silanoxyiodination of Alkenes [PDF]
The Journal of Organic Chemistry, 2021 We present the first examples of tethered silanoxyiodination reactions of allylic alcohols. The products are usefulsilanediol organoiodide synthons and are formed with high regioselectivity and diastereocontrol. The reaction is scalable greater than 10-fold without loss of yield or selectivity.

Stereo-Electronic Factors Influencing the Stability of Hydroperoxyalkyl Radicals: Transferability of Chemical Trends across Hydrocarbons and ab initio Methods [PDF]
Phys. Chem. Chem. Phys., 2023, 2023 The hydroperoxyalkyl radicals (.QOOH) are known to play a significant role in combustion and tropospheric processes, yet their direct spectroscopic detection remains challenging. In this study, we investigate molecular stereo-electronic effects influencing the kinetic and thermodynamic stability of a .QOOH along its formation path from the precursor ...

Millimetre and submillimetre spectroscopy of isobutene and its detection in the molecular cloud G+0.693 [PDF]
A&A 680, A25 (2023), 2023 Isobutene ((CH$_3$)$_2$C=CH$_2$) is one of the four isomers of butene (C$_4$H$_8$). Given the detection of propene (CH$_3$CH=CH$_2$) toward TMC-1, and also in the warmer environment of the solar-type protostellar system IRAS 16293$-$2422, one of the next alkenes, isobutene, is a promising candidate to be searched for in space.

A mild and effective method for the conversion of alkenes into alcohols in subcritical water [PDF]
Journal of the Serbian Chemical Society, 2007 Alkenes were oxidized to alcohols in subcritical water. A number of alkenes were oxidized directly to their alcohols in excellent yields. The syntheses were performed in 215 cm3 stainless steel high pressure reactor at 120 ºC in 150 cm3 water. The yields
