The rate of reaction of F atoms with a series of compounds, CH4, CH3F, CH2F2, CHF3, CHClF2, HCl, CBrF3, NH3, and PH3 has been determined relative to the chemiluminescent reaction[Formula: see text]by photometry. The fluorine atoms were produced in a flow system from the fluid mixing of molecular fluorine and nitric oxide diluted with argon.

The room-temperature mercury 6(1 23Pi) photosensitization of disilane produces H2, SiH4, Si3H8, Si4Hio, and a solid deposit. From detailed kinetic studies using deuterium-labeling techniques and scavengers such as NO and C2H4 it has been established that the sole primary step is Hg 6(3 4

The quantum yield for the mercury photosensitized decomposition of hydrogen has been measured using the ethylene scavenging technique and has been found to be equal to unity.

247ChemInform Abstract 2-Butyne-1,4-diol (I) reacts with chlorodiphenylphosphine (II), yielding 2,3-bisdiphenylphosphinyl-1,3-butadiene (V) as a result of rearrangement reactions. (Intermediates, mechanism, 1H-, 13C-, 31P-NMR-data).
