Herein Is Presented A Hammett Analysis Of The Solvolytic Lability Of Aryltrifluoroborates Where Log(K(Solv)) Values Correlate To Sigma Values With A Rho Value Of Approximately-1. This Work Provides A Predictable Rubric For Tuning The Reactivity Of Boron For Several Uses Including F-18-Labeled Pet Reagents And Has Mechanistic Implications For Arbf3-Enhanced Ligandless Metal-Mediated Cross Coupling Reactions With Aryltrifluoroborates.

专利号:WO-2024015528-A1 优先权日:2022-07-15 标题 :Efficient procedure for the synthesis of hydrazone-linked tetrahedral nanocages 发明人:SCHNEEBELI SEVERIN; VESTRHEIM OLAV 权利人:UNIV VERMONT 摘要:The present application is directed to a nanocage of Formula (I): wherein A and R are as described herein. The present application is also directed to an efficient process for preparation of a nanocage of Formula (I), which allows for efficient scale-up of the nanocage synthesis. Furthermore, this new process allows for rapid nanocage diversification, due a newly introduced late-stage functionalization method.

专利号:US-8133840-B2 优先权日:2004-06-07 标 题:Stable composite material comprising supported porous gels 发明人:MIKA ALICJA M; WANG MAGGIE SANJU; CHILDS RONALD F 权利人:MIKA ALICJA M; WANG MAGGIE SANJU; CHILDS RONALD F; NATRIX SEPARATIONS INC 摘要:This invention relates to a stable composite material comprising a support member that has a plurality of pores extending through the support member, and a macroporous crosslinked gel that is located in, and fills, the pores of the support member, in which crosslinked gel is entrapped a stabilizing polymer, which stabilizing polymer is neutral, linear or branched, non-crosslinked, and substantially water-insoluble. The presence of the stabilizing polymer is such that it allows the composite material to largely retain its porosity and morphology after being dried. The invention also relates to a process for preparing the stable composite material described above, and to its use. The stable composite material is suitable, for example, for separation of substances, for example by filtration or adsorption, including chromatography, for use as a support in synthesis or for use as a support for cell growth.
