摘要：

Away from the fold: Insertion of the terminal alkyne PhCH2C 2H (2) into the folded C3B2 heterocycle (R 2 = CH2SiMe3, Me) of the formal 16-valence-electron complexes 1 gives the 18-valence-electron boron-containing ruthenocene analogues 3 with a 4-borataborepine as 6π-electron ligand. Side products 4 and C6H3(CH2Ph)3 are detected by mass spectrometry. Compound 4 is formed directly as the only product when 1 is treated with R2C2 (R = Et, p-tolyl).
