摘要:Precursors and methods for the synthesis of mono- and difunctionalized acetylenes are described. The invention includes novel tricoordinate iodonium transfer reagents and novel alkynyldi(phenyliodonium) salts, both of which are precursors for the functionalized acetylenes. The iodonium transfer reagents take the general form of mixed iodonium sulfonates PhI + (X)OSO 2 R f , where X may be OAc, NHAc, NCO, or CN. These mixed iodonium sulfonates are produced by reaction of iodosobenzene with certain substituted trimethylsilanes. n To make the alkynyldi(phenyliodonium) salt PhI + C.tbd.CI + Ph•2 R f SO 3 - ,a mixed iodonium sulfonate is reacted with a bistin acetylene of the kind R' 3 SnC.tbd.CSnR' 3 . Alternatively, the reaction may be performed with disubstituted tin diacetylenes to produce PhI + C.tbd.C-C.tbd.CI + Ph•2 R f SO 3 - to produce a dialkynyldi(phenyliodonium) salt. Subsequent reaction of a nucleophile with the alkynyldi(phenyl-iodonium) salt or dialkynyldi(phenyliodonium) salt produces a difunctional acetylene or a difunctional 1,3-diyne, respectively.

摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.
