## Abstract The carboxamides RCONH~2~ [Rο£ΎPh (1), __t__Bu (2)] react with BEt~3~ and with (9Hβ9βBBN)~2~ to give the (acylamino)diethylboranes 3, 4 and the 9βacylaminoβ9βBBN 5, 6, respectively. Compounds 3 and 4 are largely monomeric (NMR) in solution and dimeric as crystalline solids [Xβray structur

from traces of water). Reaction of 1 with KSCN in MeCN gives exclusively the substitution product TsiSiMe,NCS, but CsF and NaN,, which are only very slightly soluble, promote very predominant isomerization. Possible mechanisms of the isomerizations are discussed. Cyanate is a markedly better leaving
## Abstract Reaction of dithioic acids with dicyclohexylcarbodiimide has been found to give the corresponding bis(thioacyl) sulfides **1** in good yield, which are very useful thioacylating reagents under mild reaction conditions. Most of the aromatic thioanhydrides (**1**, R = aromatic) are fairly
