The colourless, liquid, pyrophoric alkylalkylideneboranes R-B=CA2 (2c, d: R = Me, tBu; A = SiMe3) are formed from Me(MeO)B-CA3 and tBu(F)B-Ca3 by elimination of AOMe at 560 deg C and AF at 490 deg C, respectively.At ambient temperature 2d can be stored, whereas 2c cyclodimerizes to form 5. 2d crystallizes at 225 K; a structure determination at 120 K reveals the C-B=C skeleton to be linear with BC bond lengths of 154.7 and 136.1 pm.The adduct 6 and the cycloadducts 7a, 8 are formed from 2c and 2,6-dimethylpyridine, benzophenone, and the iminoborane tBuB*NtBu, respectively. 2d gives the cycloadduct 7b with benzophenone. - Keywords: Alkylideneboranes; Boron, two-coordinated; 1,2-Oxaboretane derivatives; 1,2,4-Azadiboretidine derivatives
