Matrix isolation study of the reaction of dimethyl sulfoxide with CrCl2O2 and OVCl3

Matrix Isolation and Theoretical Study of the Reaction of Substituted Phosphines with CrCl2O2

“…Given the experimental differences, the agreement for all of these systems is excellent, and the products of the merged-jet co-deposition for each system are identified as the substituted phosphine oxide , formed through gas-phase oxygen atom transfer from CrCl 2 O 2 to the phosphine. Oxygen atom transfer in merged jet deposition has been observed previously for the CrCl 2 O 2 + (CH 3 ) 2 SO and H 2 S systems. , These results are also consistent with the calculated Δ E 0 ° and Δ G 298 ° values shown in Table , where these values ranged from essentially thermoneutral for the PCl 3 reaction to −37 kcal/mol for the PBr 3 reaction. The observation of the uncomplexed phosphine oxide upon initial deposition in the twin-jet experiments demonstrates that the oxygen transfer reaction is very rapid and occurs with a low activation barrier.…”

Matrix isolation and theoretical investigation of the photochemical reaction of CrCl2O2 with benzenes substituted with electron withdrawing groups

“…Past studies in this laboratory have examined the matrixisolated products of the thermal and photochemical reactions of CrCl 2 O 2 , OVCl 3 , and OVF 3 with organic and inorganic substrates [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Specifically, two recent studies in this lab [33,34] examined the reactions of CrCl 2 O 2 with benzene and with methyl-substituted benzenes.…”

Infrared matrix isolation study of the oxidation of H2S by CrCl2O2

“…the oxidation of ethyne to ketene 14 ) or by expanded valence (e.g. the oxidation 15 of (CH 3 ) 2 SO to (CH 3 ) 2 SO 2 ). When this reaction occurred as a result of irradiation after deposition, the two species (e.g.…”
