A Bulky Disulfoxide Ligand for Pd-Catalyzed Oxidative Allylic C-H Amination with 2,2,2-Trichloroethyl Tosyl Carbamate

Challenging substrates and conditions in homogeneous catalysis pose stringent demands on the ligands used. A novel, bulky, 1-adamantyl-substituted disulfoxide ligand designed after a systematic evaluation of the electronic and steric properties of disulfoxide substituents permits the allylic oxidative C-N coupling reaction to proceed at lower catalyst loading while requiring a smaller excess of reagents. Additionally, this ligand improves the yields when TsNHCOOCH2CCl3, a novel reagent that permits deprotection of the products under both acidic and basic conditions, is used.

1H- And13C-NMR and electron ionization (EI) mass spectrometric study of o- And p-substituted 1,n-diarylsulfonylalkanes, XC6H4so2(CH2)nso 2C6H4X (n = 2-5, 8, 10)+

1,n-Diphenylsulfonylalkanes, PhSO2(CH2)nSO2Ph (n =2-5, 8, 10) and their o- or p-Cl or -OMe derivatives were prepared and their 1H- and 13C-NMR and EI mass spectra recorded and analyzed. The chemical shifts of the aliphatic α- and β-carbons showed a clear dependence on the o-aryl substitution, the o-Cl being the most shielding for both. Clear low-field effects were found also for the aliphatic α-protons in o-Cl and o-OMe derivatives. In case of p-OMe derivatives a palpable shielding of the aliphatic α-protons was also found similarly to the β-protons of the o-OMe derivatives. Characteristic mass spectrometric fragmentations which reflected both the influence of the aryl substitution and the length of the alkyl chain were observed and sometimes also exhibited the sulphinic acid rearrangement.

Dipole Moments and UV Spectra of some Long-chain Molecules

About one hundred compounds with long-chain molecular structure have been prepared (most of them are new).The dipole moments of four α,ω-bis(p-methoxyphenylthio)alkanes and five α,ω-bis(p-methoxyphenylsulphonyl)alkanes have been determined to find the effect of chain-length.In the case of sulphones, the observed values are compared with the values calculated for free rotation around all bonds intervening the end dipoles.The uv spectra of some 1,2-(distyrylsulphonyl)ethanes, and a number of α,ω-bis(arylsulphonyl)- and α,ω-bis(aryloxy)alkanes have been recorded to examine the applicability of the principle of chromophore additivity.
