Synthesis and photopolymerization of propenyl ether and epoxy functionalized siloxanes

Isomerization of alkyl allyl and allyl silyl ethers catalyzed by ruthenium complexes

“…(2,4,6-trimethoxyphenyl)phosphine. Other phosphine ligands, such as PPh 3 , P(o-tolyl) 3 , P(OPh) 3 , BINAP and PCy 3 were less effective for this catalytic system. The catalyst generated from {[RuCl 2 (1,5-cod)] x }, Li[AlH 4 ] and tris(2,4,6-trimethoxyphenyl)phosphine was also used in isomerization of allyl phenyl, allyl cyclohexyl, and allyl glycidyl ethers.…”

“…Although ortho-metalation of phosphine to hydride ruthenium complexes is known [40], it has been excluded on the base of the reaction of allyl benzyl ether isomerization catalyzed by {RuClH(CO)[P(Ph-d 5 ) 3 ] 3 } or by the system {[RuCl 2 (cod)] x } + P(Ph-d 5 ) 3 . No incorporation of deuterium from phosphine to propenyl chain was observed.…”

“…Also, double-bond migration catalyzed by simple ruthenium complexes is often applied in many syntheses [16,17] or as one of the steps of the tandem isomerization-RCM [18][19][20][21][22][23]. Here, we present our results of double-bond migration in alkyl allyl ethers catalyzed by [RuClH(CO)(PPh 3 ) 3 ]. 5S (Supelco) 30 m × 0.25 mm × 0.25 m; flow: constant pressure 100 kPa; temperature program: 40 • C for 1 min, 40-220 • C, 12 • C/min, 220 • C-8 min; transfer line: direct coupling to MS ion source, 250 • C constant; mass spectrometer: EI mode 70 eV ion source at 200 • C.…”

“…Cationic photopolymerized 1-propenyl ethers are of increasing importance in many industrial fields, particularly in production of various protecting and decorative coatings, inks, adhesives [1][2][3]. Synthesis of 1-propenyl ethers might be easily achieved by isomerization of allyl ethers in the presence of bases [4,5] and various transition metal complexes [6][7][8][9].…”

Photopolymerization of glycerin triglycidyl ether based systems

“…In addition, the monomers employed are generally characterized by low irritation and toxicity properties. Different types of monomers and oligomers have been proposed and reported in literature, mainly cycloaliphatic epoxides [5][6][7][8] , vinyl ethers [9][10][11][12] and propenyl ethers [13][14][15][16][17] . However, less attention has been paid to the cationic photopolymerization of glycerin triglycidyl ether.…”
