Some common heterocyclic compound, 628-77-3, name is 1,5-Diiodopentane, molecular formula is C5H10I2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. SDS of cas: 628-77-3
The tetra-TTF calix[4]pyrroles 2a-i (porphyrinogen derivatives of the present invention) were synthesized as shown in Schemes 3-1 1. Treating the monopyrroIo-TTF derivatives 1a- i with an excess of TFA and in the presence or absence of tetrabutylamonium fluoride (TBAF), tetrabutySarnonium chloride (TBACI), or tetrabutylamonium bromide (TBABr) in a mixture of CH2CI2 and Me2CO gave the tetra-TTF ca I ix[4] pyrroles 2a-i as yellow compounds in 13-55% yields. The tetra-TTF calix[4]pyrroles 2a-i were fully characterized by traditional techniques. The required monopyrrolo-TTF derivatives 1a-b were prepared according to the literature procedures (Hansen et a/ J Mater. Chem, 2004, 14, 179-184 and Jeppesen ef a/. J Org Chem. 2000, 65, 5794-5805), whereas the monopyrroio-TTF derivatives 1c- i were prepared as illustrated in Schemes 12-18.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 628-77-3, its application will become more common.
