Amine templated open-framework vanadium(III) phosphites with catalytic properties.
Four novel amine templated open-framework vanadium(III) phosphites with the formula (C(5)N(2)H(14))(0.5)[V(H(2)O)(HPO(3))(2)], 1 (C(5)N(2)H(14) = 2-methylpiperazinium), and (L)(4-x)(H(3)O)(x)[V(9)(H(2)O)(6)(HPO(3))(14-y)(HPO(4))(y)(H(2)PO(3))(3-z)(H(2)PO(4))z]·nH(2)O (2, L = cyclopentylammonium, x = 0, y = 3.5, z = 3, n = 0; , L = cyclohexylammonium, x = 1, y = 0, z = 0.6, n = 2.33; , L = cyclo...
متن کاملManganese(III)-mediated alkenyl C(sp2)-P bond formation from the reaction of β-nitrostyrenes with dialkyl phosphites.
Mn(OAc)3-mediated tandem phosphonyl radical addition to β-nitrostyrenes followed by denitration to form (E)-2-alkenyl phosphonates in good yield is described.
متن کاملElectron-rich heteroaroylphosphonates and their reaction with trimethyl phosphite.
Dialkyl heteroaroylphosphonates based on thiophene, pyrrole or furan have been prepared and their reactions with trimethyl phosphite investigated. Deoxygenation of the carbonyl groups in these heteroaroylphosphonates occurs to give carbene intermediates, which then undergo further reaction. In the case of the furan-3-oylphosphonates and those systems containing a thiophene or pyrrole ring, the ...
متن کاملChemoselective silyl transfer in the Mukaiyama aldol reaction promoted by super silyl Lewis acid.
In the silyl Lewis acid-promoted Mukaiyama aldol reaction, the steric and electronic properties of the silyl group on the silyl Lewis acid influence the reaction mechanism and product distribution. When super silyl triflates such as (TMS)3SiOTf and (TES)3SiOTf are used as Lewis acids, the silyl group of the silyl enol ether chemoselectively transfers to the product. The mechanistic details have...
متن کاملObservation of 1,3-diketones formation in the reaction of bulky acyl chlorides with methyllithium.
The formation of 1,3-diketones was observed in the reactions of bulky acyl chlorides with methyllithium. The reaction products depend on the steric hindrance around the carbonyl group of the acyl chloride and the electronic effect of the group(s) linked to the carbonyl. When the steric hindrance around the carbonyl group of the acyl chloride is big enough, the 1,3-diketone is the only product. ...
