The microwave spectrum of an unstable molecule: Chloroketene ClHCCO
摘要:
The microwave spectra of four isotopic species of the unstable molecule chloroketene ClHCCO have been observed from the flow pyrolysis of monochloroacetyl chloride and from the pyrolytic reaction of dichloroacetyl chloride with zinc metal. The spectra, which consist only of b-type transitions, were observed in the frequency range 26.5–80 GHz. Accurate rotational constants and quartic and sextic centrifugal distortion constants have been obtained for all isotopes. Large numbers of perturbations have been observed in the chlorine quadrupole hyperfine structure; consequently, the complete quadrupole coupling tensor has been evaluated. The dipole moment has been measured. The molecule has been shown to be planar, and a partial r0 structure has been determined.
This present disclosure relates to compounds with ferroptosis inducing activity, a method of treating a subject with cancer with the compounds, and combination treatments with a second therapeutic agent.

The racemic and both chiralforms of cyclopropans-1,2-d 2 and cyclopropane-1- 13 C-1,2,3-d 3 have been prepared efficiently through sequences based on trans-1,2-bis(methoxycarbonyl)cyclopropanes. These diesters have been prepared in racemicform with 1,2-d 2 labeling and with 3- 13 C-1,2,3-d 3 labeling. The labeled diesters have been resolved to provide both chiralforms, and the racemic or resolved
