An ionic Ru pincer complex was demonstrated to be highly efficient catalyst for conversion of aldoximes and aldehydes into corresponding primary amides with environmental benignity, operational convenience and catalytic loading as low as 0.5 mol%.

The cyclocondensation of the dihydroxyacetophenones (I) with cyclopropanecarboxylic chloride (II) is best performed under phase‐transfer catalysis, forming the 2‐cyclopropylchromones (III).

The transformation of aldoximes to primary amides is achieved using a pincer ruthenium complex in water under air.
