A Selective Removal of Benzyl Protecting Groups in Arylphosphate Esters with Bromotrimethylsilane

Synthetic Communications, 1992
Abstract Bromotrimethylsilane (BTMS) is shown to be an effectively selective reagent for the debenzylation of dibenzyl arylphosphate esters to give the corresponding arylphosphate acids and does not affect other functional groups also present in the molecular structure.

31P NMR kinetic study of the tandem cleavage of phosphonate esters by bromotrimethylsilane

Tetrahedron, 2010
Abstract 1H and 31P NMR methods have been used to access rate constants and activation parameters for each of the consecutive second-order silylation reactions involved in the overall transformation (1a→3a→4a), while computational optimisation of the rate constants obtained from the initial, linear phase of each reaction has permitted an excellent ...

Chloro/bromotrimethylsilane-Cu(NO 3 ) 2 ·3H 2 O: Safe and efficient reagent system for the decarboxylative ipso -nitration and dibromination of cinnamic acids

Tetrahedron Letters, 2017
Further synthetic potential of halotrimethylsilane-nitrate salt mixture is revealed. A mixture of TMSX-Cu(NO3)2.3H2O system is found to be an efficient reagent system for both the decarboxylative nitration (ipso-nitration) when X = Cl, and dibromination of cinnamic acids, with X = Br, under mild conditions.

New pyrophosphate analogues: a facile access to N-(O-alkyl-sulfamoyl)phosphoramidic acids via a simple and quantitative reaction of N-(O-alkylsulfamoyl)trimethylphospha-λ5-azene with bromotrimethylsilane and water

Tetrahedron, 2004
Abstract A new strategy to prepare pyrophosphate analogues through selective and quantitative cleavage of N -( O -alkylsulfamoyl)trialkylphospha-λ 5 -azene esters (R–O–SO 2 –NP(OR′) 3 ) has been developed. Using pure bromotrimethylsilane, N -( O -alkyl-sulfamoyl)tristrimethylsilylphospha-λ 5 -azenes (R–O–SO 2 –NP(OSiMe 3 ) 3 ) have been easily ...
