  2. Abstract We describe a copper catalyst that promotes the addition of phosphines to cyclopropenes at ambient temperature. A range of cyclopropylphosphines bearing different steric and electronic properties can now be accessed in high yields and enantioselectivities. Enrichment of phosphorus stereocenters is also demonstrated via a Dynamic Kinetic Asymmetric Transformation (DyKAT) process. A combined experimental and theoretical mechanistic study supports an elementary step featuring insertion of a CuI‐phosphido into a carbon‐carbon double bond. Density functional theory calculations reveal migratory insertion as the rate‐ and stereo‐determining step, followed by asyn‐protodemetalation.

  3. This work demonstrates that sonication, followed by polymer-wrapping, is an effective strategy to modulate the length of self-assembled nanotubes. The length distributions of the nanotubes were controlled by varying the amplitude of sonication. Wrapping the nanotubes with ionic polymers suspended the propensity of the nanotube fragments to re-assemble over time into their elongated precursors.
