Q-switched laser-induced reactions of thiacyclobutane and thiacyclopentane with oxygen 来自 ACS 喜欢 0 阅读量: 10 作者:FP Miknis,JP Biscar 摘要: The results of some investigations of the chemical reactions occurring during laser-induced gas breakdown of sulfur compounds in the presence of oxygen...
(O)RI1, or X-W-Y; m is 1 or 2; n is 0- 4 ; p is 0 or 1; X is 0, S, CH2, or NH; W is a spacer group made up of a chain of 1 to 100 atoms, and optionally also comprising of substituted carbon and/ or nitrogen atoms and optionally including oxygen or sulphur atoms...
silent in the MTHF-matrix at 80 K; (c) the lifetime of the transient was insensitive to the presence of molecular oxygen (decay trace at 580 nm, Figure 2c); and (d) the activation parameters (Table 1) are similar to those for the decay process of DRa, in particular, the high (...
Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Wash skin with soap and water. Keep victim warm and quiet. In case of burns, ...
This indicated that deuterium on C-5 of glucosamine was lost during the formation of the cyclopentane ring. In the 2H NMR spectrum of labeled allosamine prepared from (27) obtained from the feeding experiment with [6-2H2]-d-glucosamine, two deuterium signals, whose chemical shifts corresponded...

yl or 5-oxo-4H-1,2,4-oxadiazol-3-yl; and A is a group which together with the adjacent carbon-carbon double bond forms a heteroaromatic ring containing from 1 to 4 heteroatoms selected from nitrogen, oxygen and sulfur and optionally substituted. SHEJR. LYNCH JOSEPH J....
20). According to the results of NBO analysis, the diequatorial conformers are slightly more stabilized by orbital interactions than the diaxial conformers, but an electrostatic repulsive interaction between the halogen and oxygen atoms in the diequatorial conformer probably reduces the stability of ...
