A novel electrochemical esterification of alkynes for the synthesis of esters was developed in which diols and their derivatives were used as the partners. This method is green as it is catalyst-free, oxidant-free, and additive-free and shows atom-economy. This is the first example of an electrochemical reaction via cleavage of carbon-carbon triple bonds. Meanwhile, this is also the first example of a carbon-carbon triple bond cleavage reaction of alkynes with diols. This journal is
N-Acyltetrazole as an intermediate for preparation of carboxylic acid derivatives

, p. 361 - 364 (2007/10/02)
A new mild and very efficient procedure for preparation of acid derivatives via N-acyl-5-phenyltetrazole is reported. The yields are high at -10°C and purification is simple but, because of the thermal instability of the intermediate, a certain amount of corresponding oxadiazole arises if the reaction is carried out at higher temperature.
