Revisiting benzene cluster cations for the chemical

Here, benzene cluster cations were revisited as a sensitive and selective reagent ion for the chemical ionization of dimethyl sulfide (DMS) and a select group of volatile organic compounds (VOCs). Laboratory characterization was performed using both a new set of compounds (i.e., DMS, β -caryophyllene) as well as previously studied VOCs (i.e., isoprene, α -pinene).

Platinum(II) Complexes of Dimethyl Sulfide

Thermolysis of the L2PtMe2 complexes in C6D6 at 100 C results in loss of methane and formation of one major platinum-containing product in high yield. The products of thermolysis were found to be a result of cyclometalation by C-H activation of a sp3 C-H bond in the ligand to form a 6-membered ring,
