A facile access to chalcogen and dichalcogen bearing dialkylamines and diols
摘要:
A highly practical procedure for the preparation of novel classes of chalcogen bearing diamines [{H2N(CH2)n}E] and diols [{HO(CH2)n}(2)E] (n = 2 or 3 and E = Se or Te) by the reaction of disodiumchalcogenide and haloalkylamines or haloalcohols is presented.

hydroxyl (.OH) radical and three bis(alkanol)selenides (SeROH) of varying alkyl chain length, using nanosecondpulseradiolysis. .OH radical reacts with SeROH to form radical adduct, which is converted primarily into a dimer radicalcation (>Se∴Se<)+ and α‐bis(hydroxyl alkyl)}‐selenomethine radical along with a minor quantity of an intramolecularly stabilized radicalcation. Some of these radicals have been

A variety of organoselenium alkylatingagents were synthesized, using 2-hydroxyethyl and 3-hydroxypropyl selenocyanate intermediates, and studied to determine their chemical reactivities with 4-(4-nitrobenzyl)pyridine (NBP) and cytotoxicities against CCRF-CEM, L1210/0, and L1210/L-PAM cells. The comparison between the 2-chloroethyl sulfides and selenides 1-4 revealed the markedly enhanced nucleophilicity
Structural, electrochemical and oxygen atom transfer properties of a molybdenum selenoether complex [Mo2O4(OC3H6SeC3H6O)2] and its thioether analogue [Mo2O4(OC3H6SC3H6O)2]
those parameters that are directly derived from the different sizes of the varied ligandatoms (Se and S). No trans influence was observed. The metal centered redox process (Mo(V)<-->Mo(VI)) is at slightly lower voltage for the sulfur than for the selenium complex. The selenium compound catalyses the oxygenatomtransfer from DMSO to PPh(3) by a different mechanism and at a higher rate than the sulfur
A facile synthetic strategy based on enzymatic polymerization was developed to construct a ROS-responsive polycarbonate served as biocompatible drug vehicle.

omega-hydroxyalkyl selenides were synthesized in good yields under phase-transfer conditions which involved hadrazine reduction on selenium powder and then alkylation with omega-haloalkyl alcohols in the presence of TBAB, reduction the resulting diselenides with KBH4 followed by treatment with alkyl halides.
