Room-temperature reactions between the carborane nido-1-CB8H12 (1) and selected tertiary Lewis bases [L = NMe3, NEt3, and quinoline (quin)] in CH2Cl2 at room temperature for 24h resulted in the isolation of a series of 4-L-arachno-5-CB8H12 compounds (2; L = NMe3, 2a, L = NEt...
Does CH2Cl2 have a dipole moment? Does (CH3) 2O have a net dipole moment? Explain how to draw a dipole moment. Does benzene have a dipole moment? How does dipole moment help us to predict geometry of molecules? Does CH4 have a dipole moment?
Large-scale extraction and mass-directed isolation studies on the CH2Cl2/MeOH I. basta extract resulted in the purification of a new bromotyrosine-derived alkaloid, 5-debromopurealidin H (1), along with the known marine natural product, ianthesine E (2). The chemical structure of the new ...

To account for the altered emission properties of TOTA+ in ion-pair assemblies, the authors demonstrated in solution-state emission studies that formation of the simple 1:1:1 36/BF4−/ TOTA+ complex in 90:10 toluene/CH2Cl2 led to fluorescence quenching of TOTA+ fluorophore, whereas a red-...
[6]. However, a more generally applicable solution that was devised took advantage of the inclusion of the Lewis acid AlCl3to catalyze the reaction of azaindoles113–116with methyl oxalyl chloride in CH2Cl2as the solvent, as depicted in Scheme13[35,39]. This procedure provided the 4-aza (...
aPositive thermoresponsive micellar nanoreactor—at lower temperature, the polymer is soluble in water and Aldol reaction is‘off’due to the absence of suitable environment (Inset: chemical structure of the polymer). At elevated temperature, micelle is formed and provided suitable environment for L-...
(Fig. 2b). This unexpected structure of the diene suggested that these dienes might not be suitable for the Diels–Alder reactions due to twisted conjugation. Various dienophiles were examined and no cycloadduct was formed under either thermal or Lewis acid catalysis conditions. In view of the...
51 In 1990, the group of Olah reported that AlCl3/CH2Cl2 can also be used to mediate the formylation of adamantane. The formation of 1-adamantanecarboxaldehyde was believed to proceed differently from the aforementioned superacid-catalyzed formylation. Hydride abstraction of adamantane by a ClCH2δ+...
