In organic chemistry, the conversion of inactivated carbon-hydrogen (C-H) bonds to carbon-nitrogen (C-N) bonds is a highly valued transformation. Scientists can accomplish such reactions at only a single C-H site since the ...
In synthetic organic chemistry, Z-olefins are a challenging synthetic target to produce in the lab due to their relative thermodynamic instability. The Z-olefins form an unsaturated compound with a CnH2n formula that can ...
With their ability to harness the strange powers of quantum mechanics, qubits are the basis for potentially world-changing technologies—like powerful new types of computers or ultra-precise sensors.
