Gellman “Enantioselective surface chemistry of 2-bromobutane on the Cu(643)R&S and Cu(531)R&S surfaces” J.
1-Bromobutane Report - Gravity Waves
Probably the large difference in percent yield (19.96 to 40.65) is due to not enough care being taken in separating the layers and washing at each step of production of 1-bromobutane. The container should be capped and mixed thoroughly, and the separation to be complete before separating. Also, minimal product should be discarded along with the inorganic layer of the separation.
Synthesis of 1-bromobutane Essays
Other work has used 13C isotopically labelled L-aspartic acid to monitor directly the enantioselective separation of DL-aspartic acid on Cu(3,1,17)R&S surfaces (). This work generates insight into some of the fundamental phenomena that lead to enantioselective adsorption and catalysis on chiral surfaces.
Recent work in Professor Gellman’s laboratory has focussed effort on the development of instrumentation and methods for high throughput study of surface phenomena. Study of the surface science of multicomponent materials such as alloys is complicated by the fact that one needs to prepare, characterize and study many samples of varying composition. Gellman’s group has worked to overcome this bottleneck by developing tools for the preparation of Composition Spread Alloy Films. These are alloy films that have composition gradients parallel to their surfaces such that a 1x1 cm2 sample contains all possible compositions of a ternary alloy, AxByC1-x-y with x = 0 -> 1, y = 0 -> 1-x. Spatially resolved materials and surface characterization methods (SEM, EDX, EBSD, XPS, UPS, LEIS, etc.) can then be used to map and study composition dependent phenomena such as surface segregation, catalysis, dewetting, and oxidation across the entire alloy composition space ().
Another body of recent work exploits the use of spherically curved single crystal surfaces to conduct high throughput studies of structure sensitive surface chemistry that span surface orientations continuously. This circumvents the need for study of many single crystals exposing surfaces of a single crystallographic orientation. Surface Structure Spread Single Crystals expose a distribution of different surface orientations () spanning a continuous region of the stereographic projection of all possible surface orientations. Spatially resolved surface analysis methods such as STM, XPS and UPS can be used to study problems in surface structure, surface physics and structure sensitive surface chemistry.

And whereas the ministers suspect that the information concerning a significant new activity in relation to 24 of those substances may contribute to determining the circumstances in which these substances are toxic or capable of becoming toxic within the meaning of section 64 of the Canadian Environmental Protection Act, 1999;
Structure for T3D1781: 1-Bromobutane
At this time, it is proposed that the Order amending the DSL would require any person (individual or corporation) engaging in a significant new activity in relation to the substances listed in the tables below, to submit a SNAN containing all of the information prescribed in the Order at least 90 or 180 days, as specified in the Order, prior to the import, manufacture or use of the substance for the significant new activity. Potential activities with respect to the substances requiring a SNAN submission would include, but would not be limited to, the activities summarized in Tables 1–5. Tables 1–5 also summarize whether activities involving the use of the substance as a research and development substance, or as a site-limited intermediate or export-only substance (i.e. special categories) would require the submission of a SNAN. The terms “research and development substance” and “site-limited intermediate substance” are defined in subsection 1(1) of the New Substances Notification Regulations (Chemicals and Polymers). An export-only substance is a substance that is manufactured or imported in Canada and destined solely for foreign markets.
