Chemistry of 1-Fluoro-2,3,4-triphenylcyclobutadiene Dimers (2007)

Choudhury, Angshuman R, Chopra, Deepak, Guru Row, Tayur N, Nagarajan, Kuppuswamy, Roberts, John D

The reaction of 2,4-dichloro-1,1-difluoro-3-phenyl-2-cyclobutene 1 with excess phenyllithium and subsequent transformations of the products have been reinvestigated. The phenyllithium reaction...

In Situ Cryocrystallization of Diphenyl Ether: C-H...\pi Mediated Polymorphic Forms (2004)

Choudhury, Angshuman R, Islam, Kabirul, Kirchner, Michael T, Mehta, Goverdhan, Row, Tayur Guru N

Polymorphism in diphenyl ether has been identified during in situ crystallization via single-crystal X-ray diffraction. Only weak inter- and intramolecular C-H...\pi interactions control the packing...

Properties of Hydrogels Derived from Cationic Analogues of Bile Acid: Remarkably Distinct Flowing Characteristics (2004)

Sangeetha, Neralagatta M, Bhat, Shreedhar, Choudhury, Angshuman R, Maitra, Uday, Terech, Pierre

A new class of cationic bile acid derivatives was synthesized to gel water and aqueous electrolyte solutions. Investigations on these hydrogels are carried out at different length scales by a...
