A one‐pot synthesis of polysubstitutedbenzene derivatives was achieved via a platinum(IV)‐catalyzed intramolecular cycloaromatization reaction. The reaction proceeds via a tandem skeletal rearrangment, dehydration and double bond isomerization, which proved to be very useful for the syntheses of a range of interesting polyalkyl‐substitutedbenzenes.

Abstract Classical acetalation and transacetalation of sucrose (α- d -glucopyranosyl β- d -fructofuranoside) with long-chain alkyl carbonyl derivatives lead conveniently to a new class of acetals of great interest, due to their detergent properties.

A refrigeration lubricant composition contains an ester compound obtained from a polyol and a fatty acid, and a five- or six-membered ring cyclic ether compound having a side chain with an ester bonding. The content of the cyclic ether compound is adjusted to 0.01 to 5 parts by mass based on 100 parts by mass of the ester compound.
