Synthesis of novel rigid rod iron metal containing polyyne polymers
摘要:
Treatment of the dihaloiron-chelating phosphine complex, Fe(DEPE)2Cl2 (1) with 2.5 equivalents of Me3SnC=C6H5 (2) gives the monomeric complex, trans-Fe(DEPE)2(C=CC6H5)2 (3), whereas the reaction of equimolar quantities of 1 and Me3SnC=CRC=CSnMe3 (R = p-C6H4 (4); p-(CH3)2C6H2 (5)) yields soluble and high molecular weight rigid rod polymeric species, trans-[-Fe(DEPE)2(-C=CRC=C-)]n (6.7).
