摘要

2-二苯基膦苯甲醛1与13组路易斯酸反应生成简单的膦加合物C6H4P(C(O)H)(Ph)2InX3；X = Br 2和I 3。相反，Lewis酸GaCl3， AlCl3， E(C6F5)3 （E = B或Al）和ClAl(C6F5)2影响Lewis酸/膦在羰基上的加成，与八元环产物[(C6H4C(H)(OER3)P(Ph)2)]2 ER3 = Al(C6F5) 34, Al(C6F5)2Cl 5, AlCl3 6，或GaCl3 7或六元环物种(C6H4C(H)(OB(C6F5)3)P(Ph)2(C6H4C(H)(O) P(Ph)2)) 8产生两性离子。这些产物来源于挫折刘易斯对添加到醛片段充分表征和描述，并考虑了不同的反应性。

Reactions of 2-Diphenylphosphino-benzaldehyde with Group 13 Lewis Acids.

2-Diphenylphosphinobenzaldehyde 1 reacts with the group 13 Lewis acids to give simple phosphine adducts C₆H₄P(C(O)H)(Ph)₂InX₃; X = Br 2 and I 3. In contrast, the Lewis acids GaCl₃, AlCl₃, E(C₆F₅)₃ (E = B or Al), and ClAl(C₆F₅)₂ affect Lewis acid/phosphine addition to a carbonyl group, affording zwitterions with either the eight-membered ring products [(C₆H₄C(H)(OER₃)P(Ph)₂)]₂ ER₃ = Al(C₆F₅)₃ 4, Al(C₆F₅)₂Cl 5, AlCl₃ 6, or GaCl₃ 7 or the six-membered ring species (C₆H₄C(H)(OB(C₆F₅)₃)P(Ph)₂(C₆H₄C(H)(O) P(Ph)₂)) 8. These products derived from the frustrated Lewis pair additions to aldehyde fragments are fully characterized and described, and the differing reactivity is considered.

期刊介绍： Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
