McQuillinet in Exarchia, a radical and anti-authoritarian neighbourhood located within the city centre of Athens, Greece, this is an ethnography examining the social struggles and grassroots mobilizations that emerged locally during the crisis. Based on over two years of fieldwork between November 2012 and e

At a time when the economy is growing and pay levels finally rising, the necessity for more cuts in public expenditure is fiercely contested. The scope of state services, the levels of support for people in need, and the kinds of organ

Homogeneous Hydrogenation of Alkenes, Alkynes, Allenes, and 1,3-Dienes,c complex. It is a familiar observation [1] in heterogeneous hydrogenation that alkynes are generally more strongly co-ordinated than alkenes and it is also found [1] that, for an alkyne, alkyl substitution on or near the unsaturated centre may increase, and for an alkene reduce the rate of hydrogen

Dissonance

Hydrogenolysis of Cyclopropanes,found to be quite slow. Cyclopropanes are equally stable towards homogeneously catalysed hydrogenolysis, and in the studies so far reported cyclopropane hydrogenolysis by homogeneous catalysis is observed only in cases where the cyclopropyl residue is in conjugation with an alkene bond, and then to

概觀

Hydrogenation of Aromatics and Heteroaromatics, of the aromatic ring to hydrogen under these conditions. Also the survey in Chapter III of alkenes which have been hydrogenated by homogeneous catalysis included a number of examples of molecules containing a benzenoid or thiophene ring.

Catalytic Activation of Alkane Carbon-Hydrogen Bonds, stage (ii) involving hydrogenolysis of the metal alkyl, is effectively non-reversible under these conditions. The reason lies in the thermodynamic stability and lack . of polarisability of the carbon-hydrogen bond. Despite these effective stabilising factors, however, conditions have in fact been e
