摘要

The title compound N-[3,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-N-ethylnitrous amide (2, m.f. C_(20)H_(32)N2O5B2) and N-[3,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl]phenyl)-N-isopropylnitrous amide (4, m.f. C_(21)H_(34)N2O5B2) have been synthesized and characterized by elemental analysis, MS, IR, ~1H, ~(13)C, ~(11)B NMR spectroscopies. In addition, their crystal structures were determined by single-crystal X-ray diffraction. The crystal of 2 belongs to monoclinic, space group P2_1 with a = 6.3220(13), b = 28.910(6), c = 12.827(3) A, β = 102.61(3)°, Z = 4, V = 2287.8(8) A~3, D_C =1.167 g/cm~3, μ(MoK_α) = 0.081 mm~(-1), F(000) = 864, the final R = 0.0737 and wR = 0.1548 for 4209 observed reflections with I > 2σ(I), while the compound 4 crystallizes in triclinic, space group P1 with a = 6.8730(14), b = 10.827(2), c = 17.000(3) A, α = 101.30(3), β = 92.07(3), γ= 92.11(3)°, Z = 2, V = 1238.5(4) A~3, D_c = 1.116 g/cm~3, μ(MoK_α) = 0.077 mm~(-1), F(000) = 448. the final R = 0.0934 and wR = 0.1628 for 4546 observed reflections with I > 2σ(I).
