Values for the opticalrotations of enantiomerically pure 2-halogenopentanes are determined. Molecular rotations for these halides and for the previously prepared 2-halogenobutanes and 2-halogeno-octanes are reported at five wavelengths in the region 365–589 nm. and an empirical relationship between them is established.

Cascade cyclization for the synthesis of indolo[2,1-α]isoquinoline derivatives <i>via</i> visible-light-induced halogen-atom-transfer (XAT) and hydrogen-atom-transfer (HAT)
A transition metal-free photoredox cascade cyclization is herein reported. In this protocol, sustainable visible light was used as the energy source and organic light-emitting molecule eosin Y served as an efficient photocatalyst. A variety of easily available 2-aryl-N-acryloyl indoles can readily react with alkyl radicals, which are generated from organohalides and tertiary amines via either the
