The C2-symmetric bis(oxazoline)s (4S,4S)-R1-BOX, with R1 = tBu and Ph, react with ZnEt2 straightforwardly to the four-coordinate complexes ((4S,4S)-R1-BOX)ZnEt2 in high yield. Their immobil
A highly enantioselective hydrogenation of silyl enol ethers catalyzed by chiral frustrated lewis pairs
Wei, Simin,Du, Haifeng
, p. 12261 - 12264 (2014/10/16)
Using a simple combination of tri-tert-butylphosphine and chiral borane generated in situ by the hydroboration of chiral diene with HB(C 6F5)2 as a frustrated Lewis pair catalyst, a highly enantioselective metal-free hydrogenation of silyl enol ethers was successfully realized to furnish a variety of optically active secondary alcohols in 93-99% yields with 88->99% ees.

The iron-catalysed reduction of olefins has been achieved using a simple iron salt and sodium triethylborohydride. A wide range of mono- and trans-1,2-disubstituted alkenes have been reduced (91-100%) using 25 mol% iron(II) triflate, 1 mol% N-methyl-2-pyrrolidinone and 4 equivalents of sodium triethylborohydride. The reduction of alkynes to alkanes is also reported (up to 84%). Significantly, the reduction of trisubstituted alkenes has also been achieved (60-86%). Copyright
