Lewis base adducts and cyclodimers of the parent boraphosphaketene were prepared for the first time, with one adduct undergoing decarbonylation and phosphinidene insertion to form very rare 1,2-phosphaborinines, B/P isosteres of benzene. The strong donor properties of these 1,2-phosphaborinines were confirmed through synthesis of their pi complexes with Group 6 metals.
The first examples of Lewis base adducts of the parent boraphosphaketene (H2B-PCO) and their cyclodimers are prepared. One of these adducts is shown to undergo mild decarbonylation and phosphinidene insertion into a B-C bond of a borole, forming very rare examples of 1,2-phosphaborinines, B/P isosteres of benzene. The strong donor properties of these 1,2-phosphaborinines are confirmed by the synthesis of their pi complexes with the Group 6 metals.
