Using the addition of alcohols to ethyl vinyl sulfoxide, a number of 2-alkoxyethyl ethyl sulfoxides were prepared, containing the following alkyls: methyl, ethyl, isopropyl, benzyl, and cyclohexyl. With a 10 mole % excess of alcohol the extent of the reaction was 70-95%. By a polymeranalogous reaction with poly(vinyl alcohol) and poly(ethylene-co-vinyl alcohol), copolymers poly[1-hydroxyethylene (74 mole %)-co-1-(2-ethylsulfinylethoxy)ethylene (26 mole %)] and poly[ethylene (62 mole %)-co-1-hydroxyethylene (35 mole %)-co-1-(2-ethylsulfinylethoxy)ethylene (3 mole %)] were prepared; the reaction with polymer alcohols requires the use of excess ethyl vinyl sulfoxide. These polymer sulfoxides were tested as catalysts of nucleophilic substitution reactions, using reactions of 1-bromooctane with sodium phenoxide, sodium iodide and potassium thiocyanate. They are more effective catalysts than polymer sulfoxides based on crosslinked poly(styrene) under the conditions of a two-phase (S-L) and three-phase (L-S-L) catalysis.

Background Preoperative meningioma embolization may be performed with microparticles or liquid embolic agents. The pressure cooker technique (PCT) has recently been described for the embolization of brain arteriovenous malformations (AVMs). Case We present the case of a 73-year-old woman with a large frontal interhemispheric meningioma that was successfully preoperatively embolized with the PCT using Squid 12, a new ethyl-vinyl alcohol copolymer embolic agent. The PCT presents considerable advantages relative to conventional embolization techniques such as deeper and faster tumor penetration and embolization of tumors with difficult vascular access, and retrograde feeling of pial afferents may be achieved. Conclusions The use of the PCT with Squid 12 may potentially increase the effectiveness of meningioma embolization, increase tumor devascularization and improve outcomes of surgical resection.
