Bridging the generation gap : Building up molecules of considerable molecular weight in a step‐by‐step manner from small units generally consumes energy and produces a lot of waste. This is not the case here since only three steps are necessary to built a dendrimer of generation 3 ( M W around 265 000), bearing 750 phosphanyl end groups, with the production of environmentally friendly byproducts: water and dinitrogen. The scheme shows the two‐step formation of a generation 2 (G 2 ) dendrimer from components AB 5 and CD 5 .
