Multivariate statistical methods such as Cluster Analysis (CA) and Principal Component Analysis (PCA) were used for the study of distribution and sources of 16 polycyclic aromatic hydrocarbons (PAHs) in topsoils from seventeen locations in SE Romania, including industrial, agricultural and natural soils. The investigated dataset consists of concentrations of individual PAHs listed by the US Env...

Y(NO3)3.6H2O catalyzed Four-Component Reaction for the Synthesis of Highly Functionalized Pyrano[2,3-c]pyrazoles in Aqueous Medium

Journal: Journal of Applied Chemical Research 2018

Ebrahim Mollashahi, Malek Taher Maghsoodlou, Mohyeddin Safarzaei, Mojtaba Lashkari, Nourallah Hazeri,

An efficient one-pot four-component protocol for the synthesis of pyrano[2,3-c]pyrazolederivatives has been demonstrated using Y(NO3)3.6H2O as catalyst under mild condition. This isa general synthetic protocol which could be applicable to a wide range of carbonyl compoundsincluding aromatic aldehydes, isatins and acenaphthenequinone. All The reactions proceededsmoothly, ...
