Disilyl dithiophosphonates in the synthesis of open chain and cyclic organothiophosphorus compounds [PDF]

Heteroatom Chemistry, 2004
O-(Trimethylsiloxy)alkyl S-trimethylsilyl aryldithiophosphonates 7a-d were obtained by the reaction of 2,4-diaryl-1,3,2,4-dithiadiphosphetane-2,4- disulfides 5a,b with disilyl derivatives of glycols 6a,c and salicyl alcohol 6b. The reactions of mixed O,S-bis(trimethylsilyl) 2,4-di(3,5-di-tert-butyl-4- hydroxyphenyl)dithiophosphonate 1 and S-silyl ...

Synthesis and Characterization of Novel Organothiophosphorus Compounds: X‐ray Crystal Structure of H₃COC₆H₄P(OC₂H₄S)(S) Synthesized by a New Method

Zeitschrift für anorganische und allgemeine Chemie, 2006
AbstractReactions of 2,4‐bis(4‐methoxyphenyl)‐1,3,2,4‐dithiadiphosphetane‐2,4‐disulfide with hydroxy substituted compounds (R‐OH) gave rise to the formation of dithiophosphonate compounds 2, 3 and 4 [R‐OH: N‐(2‐hydroxyethyl)‐phthalimide, 1‐(2‐hydroxyethyl)pyridine and 2‐(2‐hydroxyethyl)pyrrolidine].

Lyophilization: a useful approach to the automation of analytical processes?

Journal of Analytical Methods in Chemistry, Volume 12, Issue 6, Page 267-279, 1990., 1990
An overview of the state‐of‐the‐art in the use of lyophilization for the pretreatment of samples and standards prior to their storage and/or preconcentration is presented. The different analytical applications of this process are dealt with according to the type of material (reagent, standard, samples) and matrix involved.
