The synthesis of a porphyrin with a hydrocarbon encapsulated face
摘要:
The uniquely hydrocarbon-like capped porphyrin (C70H68N4), 1i, has been successfully prepared by a high dilution reaction of pyrrole with tetrakis-1,2,4,5-[pentyl-5'-(2"-formylphenyl)]-benzene 1h in the presence of boron trifluoride etherate. The aldehyde 1h was prepared by four simultaneous Wittig condensations of a phosphonium salt, 1e, with 1,2,4,5-tetraformylbenzene, followed by reduction of the double bonds with Raney nickel and deprotection with perchloric acid.
