摘要:
在没有外部加热的情况下,由InCl 3和Li(C 5 H 5)在THF溶液中高产率地制备了纯In(C 5 H 5)3。整齐在(C 5 H ^ 5)3容易分解,在150℃,以形成在(C 5 H ^ 5)(S)和环戊二烯作为主要产品,而苯的悬浮液在回流条件下分解。In(C 5 H 5)3与PPh 3形成可分离的1:1加合物,但NMe 3,THF和Et 2O不形成稳定的加合物。与InR 3(R = Me和CH 2 CMe 3)在THF溶液中进行配体再分布反应,得到R 2 In(C 5 H 5)和RIn(C 5 H 5)2。这些杂化的有机铟(III)化合物已分离为分析纯的结晶固体,但在THF溶液中,它们形成InR 3,R 2 In(C 5 H 5),RIn(C 5 H 5)2,和In(C 5 H 5)3, 作为适当的。用单晶表征[In(C 5 H 5)3 ] n,(C 5 H 5)3 In·PPh

present the first cyclic five-membered triel(I) carbenoides E(AmIm) for E = Ga, In, Tl; AmIm = amido imidazoline-2-imine, which fill the current gap between four- and six-membered triel(I) carbenoides supported by HGiso and HNacNac. Ga(AmIm) can act as a strong σ-donor ligand in transition metal complexes, while the intermediacy of the Al(I) carbenoide Al(AmIm) is rationalised based on the isolation

The syntheses of the first main group triple-decker cations
are described, namely,
[(η5-C5Me5)Sn(μ-η5-
C5Me5)Sn(η5-C5Me5
)][Ga(C6F5)4] and
[(η6-C7H8)In(μ-η5-C
5Me5)In(η6-C7H8
)][(C6F5)3BO(H)B(C6F
5)3], both of which have been characterized by X-ray
crystallography; the former was prepared by the reaction of
Sn(η5-C5Me5)2 with
Ga(C6F5)3, while the latter was prepared
by treatment of
[In(η5-C5Me5)]6 with an
equimolar mixture of B(C6F5)3 and
H2O·B(C6F5)3.

A frustratedLewispair (FLP) chelation approach was employed to access low-valent phosphorus centers. The resulting adducts act as P atom sources for phosphinidene (PR) transfer, indiumphosphide synthesis, and neutral P2 transfer to organic substrates.

An organometallic tetrahedron-shaped indium(I) tetramer [(MeIPrCH)In]4 (MeIPrCH = [(MeCNDipp)2CCH]−; Dipp = 2,6-iPr2C6H3) supported by anionic N-heterocyclic olefin (aNHO) ligands is reported. The monomeric unit of this species exhibits both Lewis acidic and basic character at indium, while the steric profile of the aNHO ligand enables isolation of a rare monomeric imide, RInNR′.
