A new synthetic method of N-methoxy-N-methylamides is developed. The palladium-catalyzedcouplingreaction of N-methoxy-N-methylcarbamoyl chloride furnished N-methoxy-N-methylamide in moderate to good yield, wherein a carbonyl equivalent was appended to sp and sp2 carbon atoms as a versatile synthetic basis for further manipulation.

Double insertion of alkynes into the C–Sn bond of an alkynyl-, alkenyl-, allyl- or arylstannane proceeded in the presence of a palladium–diimine complex to afford highlyconjugatedalkenylstannanes with exclusive syn selectivity. Perfect regioselectivities were observed in the dimerization–carbostannylation of ethyl propiolate with a palladium–1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene complex

free‐radical hydrostannylation of alkynes has been extensively studied and while every published mechanism involves solely radical intermediates, this appears not to be correct. Trace molecular oxygen is necessary for any radical‐mediated hydrostannylation to occur with a wide selection of alkynes, thus leading to a proposed hybrid single‐electron transfer/radical propagation mechanism.
