C-Alkylation of methanetetraboronic and methanetriboronic esters Matteson, Donald S.; Thomas, Joseph R. Journal of Organometallic Chemistry (), 24 (2), CODEN: JORCAI ; Cited by: Methanetetraboronic and methanetriboronic esters constitute a new type of one-carbon synthon which bears some analogy both to malonic ester and to Wittig reagents.
These reagents show promise of extending the utility of organoboron chemistry to classes of compounds that are not compatible with hydroboration reactions. by: Deborylative alkylation reactions with chiral 1,1,2-tris-(boronates) were performed in the group of Morken, and they found that five equivalents of NaO t Bu in toluene were efficient to form the new C-C bond from one of the geminal boryl moieties.
The syn diastereoisomer was the predominant product, obtained as 1,2-diol upon oxidative workup. Vol Issue 2 Pages CC37, C39, (September ).

traboronic (64) and methanetriboronic esters, 57–6 3 gem- diborylalkanes, 26, 29, 64 and deprotonation of trialkyl- bora 66 have been found useful in a variety of syn. Reduction of the bis(9-borafluorenyl)methane 1 with excess lithium furnishes the red dianion salt Li2.
The corresponding dark green monoanion radical Li is accessible through the comproportionation reaction between 1 and Li2.
EPR spectroscopy on Li reveals hyperfine coupling of the unpaired electron to two magnetically equivalent boron nuclei (a(11B) = ± G, a(10B) = Cited by: "iv# From carbonyl derivatives Electrochemical ~uorination of acyl chlorides and esters has been used to prepare compounds of this class[ The process gives moderate yields of cyclic per~uorinated ethers\ but often results in formation of mixtures "Scheme 6# ð67JFC"01#0\ 72JFC"12#Ł[ Sulfur tetra~uoride has been shown to be e}ective for the.
