✦ Synopsis

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 group from silicon than iodide, and comparable with triflate.

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

A review of advances in the applications of the Diels-Alder reaction in organosilicon chemistry in our laboratory is presented. Using this reaction, we have synthesized a series of organosilicon monomers and polymers with polyphenyl groups and condensed rings and established a novel vulcanization sy
