摘要:与卤化碳硼烷阴离子(如 Et(3)Si[hcb(11)H(5)Cl(6)])配合使用的三烷基甲硅烷阳离子等价物可作为 Cf,C-Cl 和 C 加氢脱卤的高效长寿命催化剂-Br 与作为化学计量试剂的三烷基硅烷键合.只有 C(Sp(3))-卤素键会发生此反应.参与该反应的含 Cf 键的底物范围非常广泛,包括简单的烷基氟化物,苯并三氟化物和具有连接到脂肪链的全氟烷基的化合物.然而,Cf(4) 已证明对这种反应免疫.用一系列烷基氯和三氯化苯进行加氢脱氯,仅用伯烷基溴底物研究加氢脱溴.竞争性实验确定了催化系统在活化伯烷基卤化物中较轻卤化物的碳-卤键方面具有明显的动力学偏好.相反,在一锅实验中,C(6)F(5)Ccl(3) 的加氢脱氯比 C(6)F(5)Cf(3) 的加氢脱氟进行得快得多.et(3)Si[hcb(11)H(5)Cl(6)] 的固态结构由 X 射线衍射方法确定.

标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.
