General description

1,4-Diiodotetrafluorobenzene forms trimeric complexes as new, halogen-bonded mesogens with two molecules of alkoxystilbazole[1]. The electron density study of the halogen-bonded complex of 4,4′-dipyridyl-N,N′-dioxide with 1,4-diiodotetrafluorobenzene at 90K has been reported[2].

1,4-Diiodotetrafluorobenzene is a ditopic perfluorinated iodobenzene used for cocrystallization of halopyridinium salts.[3]

Application

1,4-Diiodotetrafluorobenzene has been used as the halogen bonding donor during the preparation of phosphorescent cocrystal with polycyclic aromatic hydrocarbons[4].

Serine hydroxymethyltransferase (SHMT) catalyzes the transfer of a β-carbon from serine to tetrahydrofolate to form glycine and 5,10-methylene-tetrahydrofolate. This reaction plays an important role in neurotransmitter synthesis and metabolism. We set out to resequence SHMT1 and SHMT2, followed by functional
