TL;DR: In this paper , a rhodium-catalyzed formal [2 + 2 + 1] annulation of alkynes with arylboronic acids to produce 1, 1 disubstituted 1(H)-indenes is developed.

Abstract: : Using colloidal particles with di ff erent thermosensitivities, we observe the transition from a crystalline solid to a disordered glass by tuning the size mismatch of the constituent particles in quasi-two-dimensional configurations. The transition is clearly identifiable by the correlation functions of the orientational order parameters and its susceptibilities. Di ff erent from typical order-to-disorder transitions such as melting, where the underlying mechanism involves the di ff usion of defects, the disordered phase in the crystal-to-glass transition grows via a nucleation process. The disordered clusters grow in size as the particle mismatch increases, and eventually percolate the whole system, which signifies the qualitative change from an ordered crystal to a disordered glass.
