Isolation and characterization of copper methylene (CuCH/sub 2/) via FTIR matrix isolation spectroscopy
The reactions of copper atoms with diazomethane in argon and nitrogen matrices at 12 K have been investigated. Fourier transform infrared studies show that copper atoms insert spontaneously into the CN bond of diazomethane in argon matrices to form unligated copper methylene, CuCH/sub 2/, and dinitrogen coordinated copper methylene, N/sub 2/CuCH/sub 2/. These two products are found to be photoconvertible; the coordinated N/sub 2/ group can be photodissociated with lambda greater than or equal to 400 nm photolysis and photoassociated with UV photolysis. A similar insertion reaction also occurs in nitrogen matrices; however, only N/sub 2/CuCH/sub 2/ is observed and the coordinated N/sub 2/ group cannot be photodissociated. Copper-diazomethane complexes, Cu(CH/sub 2/N/sub 2/), are found in both argon and nitrogen matrices. Photolyses (lambda greater than or equal to 500 nm/Ar, lambda greater than or equal to 420 nm/N/sub 2/) of these Cu(CH/sub 2/N/sub 2/) adducts lead to the insertion products.
