The phosphorus-containing peroxy species obtained on reaction of potassium superoxide with diethylchlorophosphate, as shown in equation (23), has also been used to prepare sulphones from sulphoxides76 at 20 °C in reasonable yields. 

Microwaves were used to support S-arylation of 5-substituted oxadiazoline-2-thiones <2000BMC69> and <2000M1207>. 5-(4-Pyridyl)oxadiazoline-2-thiones treated with 2-haloesters also afforded A-alkyl derivatives <2000CHE851>. A similar reaction occurred in the case of 5-pyrazolyloxadiazoline-2-thiones <2000JFA5312>. Organophosphorus derivatives of 1,3,4-oxadiazole were obtained by the reaction of bis(oxadiazolinethiones) with 0,0-diethylchlorophosphate (Scheme 21) <1998JFA1609>. 

Reaction of ThCl and UCl with diethylchlorophosphate ion (decp ) afforded Mldecp), which were apparently polymeric with —O—P—O bridges between the metal atoms. 

A suspension of 29.8 mmol of sodium hydride (55 percent oil dispersion) in 40 ml of dry dimethylformamide is treated at 20-30°C with 27.1 mmol of (S)-6-bromo-1,2,3, lla-tetrahydro-5H-pyrrolo[2,l-c][l,4]benzodiazepine-5,11 (10H)-dione, the mixture is stirred in the above temperature range for 45 min and then at -35°C 27.1 mmol of diethylchlorophosphate are added dropwise thereto. 

For calixarenes bearing hydrophobic functions at the para-positions, the introduction of polar functions can be achieved by exploiting the reactivity of the phenolic functions. For example, the di-phosphorylation of the lower rim can be achieved regio-selectively by reaction with diethylchlorophosphate in basic conditions yielding the corresponding phosphoester [19]. The ethyl groups can be removed by consecutive treatment with trimethylbromosilane and methanol.
