Practical approaches to labelling terminal alkynes with deuterium

Base catalysed exchange with sodium hydroxide, calcium oxide or N,N,N,N-tetramethylguanidine in deuterium oxide is a viable procedure for the preparation of terminally deuterated alkynes for those alkynes stable to strong base. The use of silver perchlorate as a catalyst is an alternative practical option when labelling alkynes which are sensitive to base or contain functionalities which would lead to labelling elsewhere in the molecule. Labelling with this catalyst takes place smoothly at ambient temperature in a mixture of N,N-dimethylformamide and deuterium oxide.

Herein we demonstrate that, based on the creation of dynamic nanospaces in solution by highly charged positive coordination cage of [Pd6(RuL3)8]28+, multirole and multi-way cage-confined catalysis is accomplisha
Polylithiumorganic compounds -21. On the Deproptonation of 1- and 3-Phenylpropyne as well as Phenylallene with Butyllithium. A Reinvestigation: Three Different Monoanions but one and the same Dianion

In contrast to the literature, with butyllithium only one and the same dianion - namely 7 - is formed starting with each of the three hydrocarbons 1, 4, and 6.On the other hand, upon working at low temperature in tetrahydrofuran as the solvent we were able to detect the three corresponding monoanions 9, 15, and 16, most interestingly 15 and 16 at temperatures higher then -40 deg C show rearrangement with 1,3-hydrogen shift.
