摘要：

Stoichiometric and catalytic reactions of terminal alkynes with various FLPs and Lewis acid-base adducts have been investigated. Reactions of phenylacetylene with FLPs composed of the Verkade base N[CH2CH2NPri](3)P (1) and the Lewis acids BPh 3, 9-hexyl-BBN, and 9-BBN gave [N(CH2CH2NPri)(3)PH][PhC C-BPh3] (2), [N(CH2CH2NPri)(3)PH][9-hexyl-9-PhC C-BBN] (3), and [N(CH2CH2NPri)(3)PH] [9-PhCH=CH-9-PhC C-BBN] (4). The binuclear Lewis acid-base adduct (C6F5)(3)Al-N[CH2CH2NPri]P-Al(C6F5)(3) (6) effectively catalyzed the dimerization of terminal alkynes to gem-1,3-enynes.
