  New phosphabenzenes by [4 + 2] cycloaddition of stannoles to 1-phospha-1-alkynes — determination of signs of coupling constants

  摘要：

  Stannoles bearing dialkylboryl groups in 3-position react with 1-phospha-1-alkynes P=C-(t)Bu (1) and P=C-CH(2)(t)Bu (2) by [4 + 2] cycloaddition and elimination of stannylene to give phosphabenzenes in high yield. The stannylenes oligomerise to give [R(2)(1)Sn](n) with n greater than or equal to 7 (R = Me, Et, -(CH2)(5)- or, in the case of R(1) = (t)Bu, react with the stannole itself. All phosphabenzenes are characterised by their consistent sets of NMR data. The absolute signs of the coupling constants (n)J(P-31, H-1), (n)J(P-31, C-13), (2)J(P-31, Si-29) and (2)J(Sn-119, P-31) were determined by appropriate 1D and 2D NMR experiments.

  The formation in high yields of various substituted allenes by the reaction of triethylborane with alkynyl stannanes is reported. NMR data (1H, 11B, 13C, 119Sn) of the allenes and of their derivatives prepared by the reaction of the allenes with acetic acid prove the proposed structures.
