New copper(I) and iron(II) complexes for atom transfer radical macrocyclisation reactions
De Campo, Floryan,Lastecoueres, Dominique,Verlhac, Jean-Baptiste
, p. 575 - 580 (2000)
New Cu(I) and Fe(II) complexes have been synthesized and proved to be efficient catalysts for atom transfer radical addition (ATRA) reactions. The catalytic activity was found to be greater than existing atom transfer systems based upon CuCl(bipyridine) or RuCl2(PPh3)3, for example. The addition of a reducing agent considerably improved the efficiency of the usual procedures. The Royal Society of Chemistry 2000.

experimental part, p. 102 - 106 (2009/09/06)
The possibility of preparing 1,4,5,6-tetrachloro-7,7-dimethoxybicyclo[2.2. 1]hept-5-enylmethyl haloacetates by the reaction of tetrachlorodimethoxycyclopentadiene with allyl haloacetates was examined. The effect of various factors on the product yield was studied, and the optimal synthesis conditions were found.
Synthesis of bicyclo[2.2.1]hept-5-enyl methyl esters of haloacetic acids
Kyazimova,Mamedbeili,Nagiev,Suleimanova,Khalilov
experimental part, p. 1803 - 1807 (2009/09/08)
Synthesis of norbornenyl methyl esters of a number of haloacetic acids via [4+2] cycloaddition of cyclopentadiene to allyl esters of these acids was examined. The yield and isomer composition of the synthesized compounds were examined in relation to the reaction conditions, and the best conditions for their preparation were found.
Cyclization of allyl α-halocarboxylates in the presence of metallocomplex initiators

, p. 764 - 766 (2007/10/03)
Allyl trichloroacetate and allyl 2,2-dichloropropionate, unlike allyl bromoacetate and allyl 2-bromopropionate, undergo cyclization into γ-lactones in the presence of a Fe(CO)5-amide system. All these esters undergo reductive dehalogenation under the action of the Bun3SnH-AlBN system.
ESTERIFICATION OF CARBOXYLIC ACIDS WITH ALLYL ALCOHOL
D'yachkov, A. I.,Likhterov, V. R.,Etlis, V. S.
, p. 829 - 832 (2007/10/02)
The kinetics of the esterification of substituted carboxylic acids with allyl alcohol were studied.The reaction is of first order in the catalyst and in the substrate, and the equilibrium under the investigated conditions is shifted toward the formation of the ester.The observed enthalpy of activation does not depend on the substituent, and the difference in the reactivities of the investigated compounds is determined entirely by the entropy component of the free energy.
