| Carbon-carbon bond activation reactions of asymmetric acetylene derivatives of the type L2Pt-(PhC三CR) were studied with 1,2-bis(diisopropylphosphino)ethane (dippe), 1,2-bis(di-tert-butyl-phosphino)ethane (dtbpe), and 1-iisopropylphosphino-2-dimethylaminoethane (dippdmae) chelates. (dippe)Pt(η2-PhC三CCH3)(1a), (dippe)Pt(η2-PhC三CCF3)(1b), and (dippe)Pt(η2-PhC三CC-(CH3)3)(1c) showed no thermal reactivity at 160 C, but 1b showed evidence for C-C cleavage to form (dippe)Pt(Ph)(C三CCF3) upon irradiation with UV light (>300 nm). In comparison, dtbpe analogues of thesemetal complexes, (dtbpe)Pt(η2-PhC三CCH3)(2a), (dtbpe)Pt(η2-PhC三CCF3)(2b),and (dtbpe)Pt(η2-PhC三CC(CH3)3)(2c), showed either C-HorC-C activation products upon photolysis. 2b produced (dtbpe)Pt(Ph)(C三CCF3), but 2a or 2c showed the formation of (dtbpe)Pt(D)(C6D5)(2D) by activation of the C6D6 solvent. Compounds 2a-c showed no thermal reactivity at 160 C. Two complexes with the hemilabile chelate dippdmae were synthesized and fully characterized, (dippdmae)Pt(η2-PhC三CCF3)(3b) and (dippdmae)Pt(η2-PhC三CC(CH3)3)(3c).C-C cleavage products of the type (L2)Pt(Ph)(C三CCF3) were observed only upon photolysis of compounds 1b, 2b, and 3b.不知哪位高手能把这段用方程式表示出来。急等啊! |

碳碳键的不对称类型L2Pt活化反应乙炔衍生物(公约与肝癌三),研究了1,2 -双(diisopropylphosphino)乙烷(dippe),1,2双(二叔丁基膦)乙烷(dtbpe),和1 iisopropylphosphino - 2 -二甲基氨乙基(dippdmae)螯合物。 (dippe)铂(η2-肝癌三CCH3)(1A)款,(dippe)铂(η2-肝癌三CCF3)(1B)条, 和(dippe)铂(η2-肝癌三消委会(异丙醇)3)(集成电路)显示,在160 C否热反应,但1b中显示,消委会裂解形成(dippe)铂(电话)(丙三CCF3)有证据紫外线照射(“300纳米)。相比之下,dtbpe类似物的thesemetal物,(dtbpe)铂(η2-肝癌三CCH3)(甲),(dtbpe)铂(η2-肝癌三CCF3)(乙)和(dtbpe)铂(η2-肝癌三消委会(Ch3和)3)(2C型),显示为C -何 钢筋混凝土- C激活产品受光。 2B条生产(dtbpe)铂(电话)(丙三CCF3),但2A或2C型显示了(dtbpe)铂(丁)(C6D5)(二维由C6D6激活)溶剂的形成。化合物甲- ç显示,在160长与hemilabile两个螯合dippdmae物没有热反应,合成了充分的特点,(dippdmae)铂(η2-肝癌三CCF3)(3B)及(dippdmae)铂(η2-肝癌三消委会(Ch3和)3)(3C)款。消委会的类型分解产品(二级)铂(电话)(丙三CCF3)只有在观察化合物1b中,乙,和3B光 |
