28598618-2	2017	This new methodology involves tandem (Ar)O-C(sp3) bond cleavage and C(sp2)/C(sp3)-SO2 formation toward divergent synthesis of sulfonyl- and phosphinyl-bifunctionalized 1,3-butadienes or allenes, depending on the substitution at the terminal carbon atoms of allenylphosphine oxides.	1,3-butadiene	168-182	Sp2 transcription factor	Homo sapiens	68-73	
18275171-1	2008	The bond length of a carbon-carbon sp2-sp2 sigma-bond without the perturbing effects of pi-interactions has been estimated by high level calculations on two prototypical systems: a 90 degrees -twisted form of butadiene and the tub conformer of cyclooctatetraene.	1,3-butadiene	209-218	Sp2 transcription factor	Homo sapiens	35-38
