  Stoichiometric and Homogeneous-Catalytic Diboration of the NN Double Bond of Azobenzene

  摘要：

  The diboration of the N=N double bond of azobenzene was achieved by reaction of the [3]diboraplatinametalloarenophanes derived from ferrocene, [Fe(eta(5)-C(5)H(4))B(NMe(2))Pt(PEt(3))(2)B(NMe(2))( eta(5)-C(5)H(4))], and bis(benzene)chromium, [Cr(eta(6)-C(6)H(5))B(NMe(2))Pt (PEt(3))(2)B(NMe(2))(eta(6)-C(6)H(5))], with an excess of azobenzene in toluene at elevated temperature. The formation of the anticipated ansa-bis(boy)hydrazines was substantiated by the determination of the molecular structure of the chromium derivative by X-ray diffraction. The synthesis of the ansa-bis(boryl)hydrazine derivative of ferrocene could also be accomplished under homogeneous catalysis conditions. Hence, reaction of the well-known [2]boraferrocenophane, [Fe(eta(5)-C(5)H(4))(2)B(2)(NMe(2))(2)], and azobenzene in the presence of 5 mol % [Pt(PEt(3))(3)] afforded the bis-borylated hydrazine derivative in good yields.

  Synthesis and Structure of [Cr{(η⁶-C₆H₅)₂B{NtBu(SiMe₃)}}] and [Cr{(η⁶-C₆H₅)₂(BNMe₂)₂}], the First Boron-Bridged Metalloarenophanes

  摘要：

  Reaction of [Cr(eta(6)-C6H5Li)(2)].tmen with (RR')-NBCl2 (R = R' = SiMe3; R = R' = iPr; R = SiMe3, R' = tBu) and B2Br2(NMe2)(2), respectively, in hexane yielded the strained [1]borachromoarenophanes [Cr{(eta(6)- C6H5)(2)-BNRR'}] (4a-c; R = R' = SiMe3; R = R' = iPr; R = SiMe3, R' = tBu) and [2]borachromoarenophanes [Cr-{(eta(6)- C6H5)(2)(BNMe2)(2)}] (5), respectively, in moderate yields as dark red solids; compounds 4c and 5 were structurally characterized. 4c exhibits the largest arenearene tilt angle (26.6(3)degrees) reported for any [n]metal-loarenophane.
