Effects of ultrasounds in polymer chemistry are relatively less explored. Sonochemistry of polymers consists of three main fields the degradation and modification of polymers, the ultrasonically assisted synthesis of polymers and the determination of the polymer structure. Special attention has been devoted to ultrasound induced chain degradation [3, 4] and to the ultrasonically influenced preparation of anionic initiators and anionic polymerization [17].

To elaborate selective approach to the compounds 25 and to increase their yields, the authors of [50] applied microwave-assisted reaction in ethanol as described earlier in [38] (see Scheme 6). However, the selective procedure for the synthesis of the heterocycles 26 was not published in this article. It was achieved by other authors [54] with the help of ultrasonication, being equally with microwave-assisted synthesis as one of the most facile tool in the modem organic chemistry [55-57]. It was established that three-component reaction of 3-amino-5-alkylthio-... 

The use of ultrasonic techniques in virtually every field of chemistry has expanded greatly in recent years. Sonochemical methods have probably been most successful for heterogeneous reactions in general and, in particular, for organometallic synthesis. Ultrasonic synthesis allows the use of safer solvents that need not be anhydrous, cheaper chloride starting materials and, frequently, lower reaction temperatures. An excellent review-on the use of sonochemistry in organic and organometallic chemistry is that of Einhorn and co-workers [141]. A second Einhorn publication on the ultrasonically assisted Barbier reaction is also very informative [142],...

Ultrasonic spray synthesis is also identified under the synonyms ultrasonic spray pyrolysis (USP) and ultrasonic spray combustion (USC). In the case liquid droplets are employed for material synthesis (as it is considered here) against the case of spray drying, salt-assisted USP or chemical aerosol flow synthesis (CAFS) have also been used.

The use of ultrasonic irradiation for producing nanomaterials has been a research topic of great interest (Dhasn et al., 1999). This is due to the simplicity of sonochemical method, the cheap price of the equipment and that in many cases the as-prepared material is obtained in the crystalline phase. The ultrasonic-assisted aqueous room tempjerature ionic liquid method was applied to prepare zinc sulfide and zinc oxide nanomateiials (Zheng et al. 2010 Jia et al. 2010), among many other nanomatreials. Selection of the room temp>erature ionic liquid was mainly based on the fact that it can be obtained at a relatively low price and the method for its synthesis is simple.
