A metal and base free synthesis of primary amines has been developed at ambient temperature through ipso amination of diversely functionalized organoboronic acids, employing a combination of [bis(trifluoroacetoxy)iodo]benzene (PIFA)-N-bromosuccinimide (NBS) and methoxyamine hydrochloride as the aminating reagent. The amines were primarily obtained as their trifluoroacetate salts which on subseq...

Generating promising materials for the conversion of CO2 to valuable industrial products under mild conditions is important both ameliorating greenhouse effect and sustainable development. Pillar[5]arene-incorporated have recently emerged as building frameworks construct versatile functional polymeric materials. Herein, we demonstrate that highly efficient fixation cyclic carbonates can be achi...

Abstract: The present work is conducted to investigate the effect of texture and carbonate content on internal friction angle of carbonate soils. Carbonate soils are majorly found in the bed of shallow waters and also offshores in tropical regions. Recently there is a huge construction projects including oil and gas extraction platform and facilities, harbors, refineries, huge bridges and ot...

The mantle sequence serpentinized peridotites of north of Nain have been converted to carbonate- silica assemblage known as listwaenite at various temperature and pH in response to CO2 and SiO2 bearing fluids. On the basis of carbonate and silica minerals content, three types of listwaenite have been recognized: carbonate, carbonate- silica and silica listwaenites. Generaly carbonate minerals a...
