How will you bring about the following conversions? 13C{1H} NMR (151 MHz, CD2Cl2): δ 174.6 (d, 1JRhC = 39, NCN), 174.0 (d, 1JRhC = 37, NCN), 162.3 (q, 1JCB = 50, ArF), 158.9 (s, py), 157.3 (s, py), 142.7 (d, 1JRhC = 32, Ph), 140.8 (s, Ph), 140.4 (s, py), 137.3 (s, Ph), 135.4 (s, ArF), 129.4 (qq, 2JFC = 32, 3JCB = 3, ArF), 127.6 (s, 2 × Ph), 127.0 (s, py), 126.3 (s, py), 125.2 (q, 1JFC = 272, ArF), 125.0 (s, NCH), 124.3 (s, NCH), 123.6 (s, Ph), 121.4 (s, NCH), 121.0 (s, NCH), 118.0 (sept, 3JFC = 4, ArF), 56.1 (s, CH2), 55.6 (s, CH2), 39.2 (s, OSMe2), 38.9 (s, NCH3), 38.0 (s, NCH3). • Accession Codes: CCDC 2022453–2022456 contain the supplementary crystallographic data for this paper. Preparation of [Rh(CNC‐Me)(Ph)Cl(OSMe2)][BArF4] (4). The hydroboration-oxidation of propene gives 1-propanol. Numbers and Quadratic Equations, Introduction Explain the preparation of the following compounds: 1. How is chlorobenzene converted into diphenyl/biphenyl? 2-Bromobutane to But-2-ene. A solution of 1 (26.2 mg, 20.0 µmol) and biphenylene (3.04 mg, 20.0 µmol) in DFB (0.5 mL) was heated at 50 °C for 16 h. The resulting solution was layered with hexane to afford the yellow crystalline product on diffusion. (ii)Add ammoniacal solution of silver nitrate (Tollen’s reagent) to both the compounds, HCOOH gives silver mirror but CH 3 COOH does not.. C) CH 3 CHO < CH 3 CH 2 OH < CH 3 COOH Or 232, Block C-3, Janakpuri, New Delhi, 2HBr (100 mg, 0.293 mmol), Na[BArF4] (284 mg, 0.320 mmol), and Ag2O (70.0 mg, 0.303 mmol) in CH2Cl2 (5 mL) was stirred in the absence of light for 18 h. The solution was filtered through a Celite plug and added dropwise to a stirred solution of [RhCl(SOMe2)3] (92.2 mg, 0.293 mmol) in CH2Cl2 (2 mL).
