英文摘要	973 Program [2012CB821704]; National Nature Science Foundation of China [20972129]; Science Foundation of Ministry of Education of China [2009060011500466]; Innovative Research Team Program [IRT1036]; The aryl(silyl)aminotrichlorosilane 2,6-iPr(2)C(6)H(3)N(SiMe2Ph)SiCl3 (1) and aryl(phosphanyl)aminotrichlorosilane ArN(PPh2)SiCl3 (Ar = 2,6-iPr(2)C(6)H(3) (2), 4-MeC6H4 (3), 2,4,6-Me3C6H2 (4)) were prepared and utilized for investigation in reactions with freshly prepared lithium alkynyls. Reaction of 1 with PhC CLi resulted in the compounds PhMe2SiC CPh and 2,6-iPr(2)C(6)H(3)N[Li(THF)(3)]-Si(C CPh)(3) (5), while 2 reacted with R'C CLi to produce the compounds Ph2PC CR' and [2,6-iPr(2)C(6)H(3)NSi(C CR')(2)](2) (R' = Ph (6), tBu (7), CH2CH2Ph (8)). Reaction of 3 with PhC CLi led to the formation of Ph2PC CPh and [4-MeC6H4NSi(C CPh)(2)](3) (9a) as a major product and {4-MeC6H4NSi(C CPh)[N(4-MeC6H4)Si(C CPh)(3)]}(2) (9b) as a minor product. When 4 was reacted with PhC CLi, [2,4,6-Me3C6H2NSi(C CPh)(2)](2) (10a) was isolated as the major product while [(2,4,6-Me3C6H2)(3)N3Si2(C mCPh)(4)Li(THF)](-)[Li-(THF)(4)](+) (10b) was the minor product. The formation of Ph2PC CPh was also detected. All reported compounds were characterized by multinuclear NMR (H-1, C-13, Si-29, and/or P-31) and/or IR spectroscopy, and compounds 2, 5-8, 9a, and 10b were further distinguished by single-crystal X-ray crystallography. These results exhibit a route to the Si2N2- or Si3N3-based cyclosilazanes 6-8, 9a, 9b, and 10a via the N-P bond cleavage of the aryl(phosphanyl)aminotrichlorosilanes during multiple metathesis reactions.
