Treatment of (dpp-Bian)Ga-Ga(dpp-Bian) (1) (dpp-Bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) with iodine gives (dpp-Bian)Ga(I)-Ga(I)(dpp-Bian) (2), which reacts in situ with K(C5H4CH2CH2NMe2) (KCpDo) or K(OCH2CH2NMe2) (KORDo) to produce the monomeric species (dpp-Bian)GaCpDo (3) and (dpp-Bian)GaORDo (4), respectively. Complex 3 reacts with PhCi≡CH to give the paramagnetic derivative (dpp-Bian)Ga(Ci≡CPh)2 (5), while compound 4 is inert toward this alkyne. In contrast, monomeric (dpp-Bian)Ga(S2CNMe2) (6) reacts with PhCi≡CH and HCi≡CH to give the cycloaddition products [dpp-Bian(PhC=CH)]Ga(S2CNMe2) (7) and [dpp-Bian(HC=CH)]Ga(S2CNMe2) (8). The related compounds [dpp-Bian(MeC=CC(O)OMe)]Ga(S2CNMe2) (9) and [dpp-Bian(CH2CH=C(Me)O)]Ga(S2CNMe2) (10) have been obtained in the reactions of complex 6 with methyl 2-butynoate and methyl vinyl ketone, respectively. New complexes have been characterized by 1H NMR (3, 4, and 7-10) and ESR (5) spectroscopy; their molecular structures have been established by single-crystal X-ray analysis. The catalytic activity of complex 6 in the hydroamination and hydroarylation of alkynes has been examined.

Acetylene, phenylacetylene, and alkylbutynoates add reversibly to (dpp-bian)Ga-Ga(dpp-bian) (dpp-bian=1,2-bis[(2,6-diisopropylphenyl)-imino] acenaphthene) to give addition products [dpp-bian(R1C=CR 2)]Ga-Ga[(R2C=CR1/
Palladium-catalyzed aerobic oxidative cyclization of N-aryl imines: Indole synthesis from anilines and ketones
Wei, Ye,Deb, Indubhusan,Yoshikai, Naohiko
supporting information; scheme or table, p. 9098 - 9101 (2012/07/14)
We report here an operationally simple, palladium-catalyzed cyclization reaction of N-aryl imines, affording indoles via the oxidative linkage of two C-H bonds under mild conditions using molecular oxygen as the sole oxidant. The process allows quick and atom-economical assembly of indole rings from inexpensive and readily available anilines and ketones and tolerates a broad range of functional groups.
