equiv of sodium diisopropyl phosphite in THF produces diisopropyl 1-(diisopropoxyphosphinyl)ethylphosphonate with excellent yield. It was found that diacyloxyiodobenzene/PR3 system may serve as an acylating agent; the acylation process can proceed via carboxylic acid anhydride or acylphosphonium salt 17 depending on the protocol used.

An acceptorless dehydrogenative methodology for the synthesis of amides, aldehydes and ketones from hemiaminal and alcohols in the presence of manganese(I) based photocatalyst is developed. Several aromatic, aliphatic, heterocyclic aldehydes and primary aryl amines as well as secondary alkyl amines were coupled, providing the corresponding amides. The methodology was also extended for dehydrogenation
