The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...

noindent We have two goals in this paper. First, we investigate and construct cofree coalgebras over $n$-representations of quivers, limits and colimits of $n$-representations of quivers, and limits and colimits of coalgebras in the monoidal categories of $n$-representations of quivers. Second, for any given quivers $mathit{Q}_1$,$mathit{Q}_2$,..., $mathit{Q}_n$, we construct a new quiver $math...

introduction canola is the world third oil crop with 25 to 55 percent oil content (hezbavi & minaei, 2008). in recent years, tendency towards expansion of the acreage of canola in iran has been increasing and for the years 2010-2011 an area of 93000 ha with a total production of 190000 tons has been reported (ministry of jihad of agriculture, 2013). application of biological fertilizers which a...
