“…Recently, n BuSeH has been shown to be an effective chain-transfer agent for the chain-transfer polymerization (CTP) of vinylarenes . Alkaneselenols have been used as capping ligands for nanoparticles and metal surfaces (akin to the use of thiols as self-assembled monolayers), − and the mechanism of the surface binding of n HexSeH on a Au(111) surface has been modeled via density functional theory (DFT) . Acylselenols [RC(O)SeH; R = Me, F 3 C, F 2 CH and F 2 ClC; 1267 − 1270 ], − H 2 C=CHSeH ( 1271 ), HCCCH 2 SeH ( 1272 ), HCCCH 2 CH 2 SeH ( 1273 ), H 2 C=CHCH 2 SeH ( 1274 ), , and H 2 CCCHSeH ( 1275 ) were prepared and their structures interrogated in the gas phase via microwave spectroscopy.…”
