Sulfonyl isocyanides RSO2NC

open access: yes, 2017
Flash vacuum pyrolysis (FVP) of 5-azido-1-aryltetrazoles results in triple N2 elimination and formation of aryl isocyanides RNC, which rearrange in part to aroylnitriles RCN under the reaction conditions.

Leuckart-Wallach Approach to Sugar Isocyanides and Its IMCRs [PDF]

open access: yes, 2015
We utilize our recently introduced Leuckart-Wallach approach to synthesize anomeric sugar isocyanides in good overall yields and two steps. Moreover, we show the general usage of these isocyanides in isocyanide-based multicomponent reactions (IMCRs) to ...

The reaction of arylmethyl isocyanides and arylmethylamines with xanthate esters: a facile and unexpected synthesis of carbamothioates

open access: yesBeilstein Journal of Organic Chemistry, 2020
An unexpected formation of carbamothioates by a sodium hydride-mediated reaction of arylmethyl isocyanides with xanthate esters in DMF is reported. The products thus obtained were compared with the carbamothioates obtained by the sodium hydride-mediated ...
