Study on the initiation step of 2-(9-carbazolyl)ethyl glycidyl ether polymerization by K−, K+ (15-crown-5)2

Decomposition of vinyl ethers by alkalide K−, K+(15-crown-5)2 via organopotassium intermediates

“…4.6. Benzyl butyl ether (16), benzyl phenyl ether (6), and tetraethylene glycol benzyl vinyl ether (7) Their GC-MS and NMR spectra have been reported in [6,7,14], respectively.…”

“…Then, it was found that the regioselective cleavage of the alkyl-oxygen bond occurred also in methyl phenyl ether, ethyl phenyl ether [2], and allyl phenyl ether [3] in their reactions with K À , K þ (15-crown-5) 2 1. It was shown in further works that various cyclic ethers as monosubstituted oxiranes [3][4][5][6][7][8][9], oxetane [10][11][12] and tetrahydrofuran [13,14] can also be opened by alkalides. The most interesting seemed to be the reaction involving oxiranes.…”

“…The most interesting seemed to be the reaction involving oxiranes. The oxacyclic ring was opened in the a- [8,9] or in the b-position [3][4][5][6]9], i.e. between the substituted carbon atom and oxygen or between the CH 2 group and oxygen, respectively.…”

Novel concept of polymers preparation with high photoluminescent quantum yield

“…Carbazole polymers have previously been prepared from cyclic monomers, that is, carbazolyl-substituted oxiranes [20][21][22][23][24]. In this work, we proposed a new idea for the synthesis of photoluminescent polymers based on utilizing as a polymerization initiator a compound bearing a carbazolyl group and prepared a range of carbazole polymers.…”

Electron-transfer reduction of selected alcohols with alkalide K−, K+(15-crown-5)2 via organometallic intermediates

“…They are known as two-electron-transfer species [5], used in the reactions with alkenes [6][7][8][9], alkines [10], alkyl halides [11,12], silyl halides [13], ketones [14,15], esters [16][17][18][19][20], and ethers [12,[20][21][22][23][24][25][26][27][28]. Organometallic compounds were intermediate products in those systems.…”
