title: Facile Syntheses of Titanium(II), Tin(II), and Vanadium(II) Porphyrin Complexes through Homogeneous Reduction. Reactivity of trans-(TTP)TiL(2) (L = THF, t-BuNC).
abstract: Facile syntheses of the meso-tetra-p-tolylporphyrin (TTP) complexes trans-(TTP)Ti(THF)(2) (1), (TTP)Sn (2), and trans-(TTP)V(THF)(2) (3) are achieved through homogeneous reduction of high-valent precursors using NaBEt(3)H. The composition of the new compound trans-(TTP)Ti(THF)(2) was determined by spectroscopic and chemical characterization. Ligand displacement reactions of trans-(TTP)Ti(THF)(2) with t-BuNC produced a new Ti(II) complex, trans-(TTP)Ti(t-BuNC)(2). The ligand-binding preference of (TTP)Ti(II)L(n)() (n = 1, 2) is picoline approximately pyridine > t-BuNC > PhC&tbd1;CPh > EtC&tbd1;CEt > THF.
