PMID: 26230834
J Org Chem. 2015 Sep 04;80(17):8821-9. doi: 10.1021/acs.joc.5b01205. Epub 2015 Aug 24.

We disclosed therein a new reaction of reductive isomerization of methylenecyclopropanes (MCPs) to vinylcyclopropanes (VCPs). On treatment with sodium metal in liquid ammonia, MCPs bearing a C-O bond at allylic position undergo both a reductive cleavage of the C-O...

Analysis of experimental depolarizing Mueller matrices through a hybrid decomposition.

Applied optics

Martin L, Le Brun G, Le Jeune B, Pellen F, Rivet S.
PMID: 25967003
Appl Opt. 2015 Jan 01;54(1):27-36. doi: 10.1364/AO.54.000027.

We propose a new decomposition for depolarizing Mueller matrices. This decomposition, which consists of a product of four basic optical devices (two diattenuators, a retarder, and a depolarizer) is derived from a previous one known as "symmetric decomposition" [J....
