| Popis: | 93 Part 1 The synthesis and characterization of organotin compounds Reactions of kitiminate salt with SnCl2 or SnCl afforded (OCMeCHCMeNAr)2SnCl2 (1)、(OCMeCHCMeNAr)2Sn (2) and (OCMeCHCMeNAr)2SnCl (3). (OCMeCHCMeNAr)2SnI2 (4) was prepared in good yields via the direct ox-addation reaction of 2 with I2. Similarily, reacting SnCl2 with 1 or 2 equiv. of pyrrolyl generated [C4H3N(CH2NMe2)–2]SnCl (5) and [C4H3N(CH2NMe2)–2]2Sn (6). [C4H3N(CH2NMe2)–2]SnBu3 (7) were prepared via the reaction of pyrrolyl salt with Bu3SnCl. All new organotin compounds were characterized by 1H, 13C NMR and elemental analysis, and compound 1, 2, 3, 4 and 6 have also been determined in X-ray crystallographic studies. Part 2 The reaction of Al-H compounds containing pyrrolyl ligand A new series Al complexes [C4H3N(CH2NMe2)–2]2Al(NHAr) (9, Ar=2,6–Me2C6H3；10, Ar=2,6–Cl2C6H3)、[C4H3N(CH2NMe2)–2]2Al(OAr) (11, Ar=2,6–tBu2C6H3；12, Ar = 2,6–tBu2–4–MeC6H2) were easily synthesized by reacting Al-H with corresponded phenol and aniline via elimination of hydrogen. All new Al compounds were characterized by 1H, 13C NMR and elemental analysis, and compound 9 and 11 have also been determined in X-ray crystallographic studies. |
